DAC0832 Digital-to-Analog Converter

Digital-to-analog converters (DACs) are often built into microcontrollers but tend to be slow, noisy, and lack resolution. So, we frequently use specialized DAC chips.

Today's example is a digitally controlled voltage regulator module that could be used in a lab power supply. The workhorse here is the LM317T chip, which has the DAC0832 digital-to-analog converter at its core.

The DAC0832 is a pretty advanced chip, with not one but two latches arranged in sequence. This setup allows it to store digital data from the microprocessor bus and convert it to an analog value at just the right moment.

In the post about the 74HC374 latch, we used it to freeze the readings on seven-segment displays for a second while counting input pulses.

After a second, the data from the counters was sent out to the display decoders, showing the frequency of the input signal measured a second earlier. Meanwhile, the next count of pulses was happening. This made for a good frequency counter.

Each of the two latches in the DAC0832 can be made transparent, meaning asynchronous. In this mode, data from the input instantly appears in the output.

A logic high on the ¬LE (¬LATCH ENABLE) pin is needed to set the input latch to transparent asynchronous mode. You could call it LATCH DISABLE without the ¬ sign.

¬LE = ILE & (¬¬CS & ¬¬WR1) = ILE & ¬(¬CS | ¬WR1).

In simpler terms, you need a logic high on the ILE (INPUT LATCH ENABLE) input and a logic low on at least one of the two inputs, ¬CS (¬CHIP SELECT) or ¬WR1 (¬WRITE1). The ¬WRITE1 and ¬WRITE2 inputs are used for strobe signals.

For the 8-bit DAC latch register, the logic for ¬LATCH ENABLE is more straightforward:

¬LE = ¬¬XFER & ¬¬WR2 = ¬(¬XFER | ¬WR2).

So, you need a low logic level on at least one of the inputs: ¬XFER (¬TRANSFER) or ¬WR2 (¬WRITE2).

The heart of the DAC0832 is the analog-to-digital converter. This analog multiplexer switches precision silicon-chromium resistors deposited on a silicon chip.

This manufacturing technique ensures high accuracy and temperature stability, which is why we use DAC chips in our favorite high-fidelity audio gear.

Plus, a multiplexer can work much faster than pulse-width modulation (PWM) analog-to-digital conversion, which we often use in Arduino DIY projects.

Also, PWM produces square pulses with different duty cycles with a broad frequency spectrum. The frequencies might be inaudible, but their interference with other frequencies in the device can create audible noises, which can be pretty unpleasant.

The homemade tube amplifier article mentioned that asymmetrical and softly clipped waveforms sound pleasant and musical to human ears because they're full of even harmonics.

But a square, symmetrical waveform has many odd harmonics, which aren't so nice to listen to, especially when they create dissonance with the overtones of other sounds played at the same time.

The DAC0832 needs an external operational amplifier to convert the current through switched precision resistors into an output voltage.

We'd probably go with the NE5532 for audio output, which we used for a simple, affordable, and high-quality headphone amp.

But the good old LM358 will do fine for a power supply. Here, op-amp IC4A converts the output current of the DAC0832 into voltage, and IC4B amplifies the resulting signal by six times.

The TL431 chip generates the DAC0832's reference voltage, which is adjusted with the potentiometer RP1. The voltage ranges from 5×1100/1200=0.42V to 4.58V.

The output of IC4B is connected to the adjustment input of the LM317. Therefore, this chip's output voltage, and therefore our homemade power supply's, will be 1.25 volts higher than IC4B's.

So, the output voltage formula is:

Vout = 1.25 + 6 * Vref * DIGITAL INPUT / 256 = 1.25 + 0.024 * Vref * DIGITAL INPUT.

Adjusting the reference voltage can change the increment and decrement steps when pressing the corresponding buttons on the power supply's front panel.

The digital value for converting to a voltage is set by two 74HC193 four-bit up/down counters.

These are presettable counters, similar to the ones we used as registers in our DIY 4-bit CPU.

Each CPU's four registers used one SN74HC161L chip as a latch. The increment function was only used in the program counter (PC) register. The other three registers disabled it by grounding the CEP and CET control inputs.

We used the decrement function in a countdown timer that could be set to any number of seconds from 0 to 99.

Thanks to the preset function, the chosen value from the PRESET ROM of our electronic traffic light tells the second counter how long the current signal combination should last. The decrement function was also used there.

In today's power supply, we do not use the preset function but both increment and decrement counting. There's also a reset button to set both counters to zero.

Accordingly, the digital-to-analog converter will also be set to zero since both of its internal latches are permanently in transparent asynchronous mode.

To lock the chip in this mode, the ¬CS, ¬WR1, ¬WR2, and ¬XFER control inputs are soldered to ground.

We could make a power supply with non-volatile preset memory if we used a microcontroller instead of up/down counters. The microcontroller's analog-to-digital converter could be used for the voltmeter and ammeter.

And if the microcontroller doesn't have enough pins to connect the 8-bit DAC data bus, we could use a shift register for serial data transfer.

In this case, the DAC0832's latch registers could be very handy if the shift register doesn't have a built-in latch.

After all, to convert a binary number into a voltage, you must wait until the binary number is fully received from the microcontroller via the serial bus. Otherwise, you’d get meaningless voltage jumps, which are unacceptable in a power supply.

Reading About the Analog vs. Digital Signals | Soukacatv.com

Overview

We live in an analog world. There are an infinite amount of colors to paint an object (even if the difference is indiscernible to our eye), there are an infinite number of tones we can hear, and there are an infinite number of smells we can smell. The common theme among all of these analog signals is their infinite possibilities.

Digital signals and objects deal in the realm of the discrete or finite, meaning there is a limited set of values they can be. That could mean just two total possible values, 255, 4,294,967,296, or anything as long as it’s not ∞ (infinity).

Working with electronics means dealing with both analog and digital signals, inputs and outputs. Our electronics projects have to interact with the real, analog world in some way, but most of our microprocessors, computers, and logic units are purely digital components. These two types of signals are like different electronic languages; some electronics components are bi-lingual, others can only understand and speak one of the two.

In this tutorial, we’ll cover the basics of both digital and analog signals, including examples of each. We’ll also talk about analog and digital circuits, and components.

Suggested Reading

The concepts of analog and digital stand on their own, and don’t require a lot of previous electronics knowledge. That said, if you haven’t already, you should peek through some of these tutorials:

Voltage, Current, Resistance and Ohm’s Law

What is a Circuit

And     some mathematics concepts: reading graphs, and understanding the     difference between finite and infinite sets.

Analog Signals

Define: Signals

Before going too much further, we should talk a bit about what a signal actually is, electronic signals specifically (as opposed to traffic signals, albums by the ultimate power-trio, or a general means for communication). The signals we’re talking about are time-varying “quantities” which convey some sort of information. In electrical engineering the quantity that’s time-varying is usually voltage (if not that, then usually current). So when we talk about signals, just think of them as a voltage that’s changing over time.

Signals are passed between devices in order to send and receive information, which might be video, audio, or some sort of encoded data. Usually the signals are transmitted through wires, but they could also pass through the air via radio frequency (RF) waves. Audio signals, for example might be transferred between your computer’s audio card and speakers, while data signals might be passed through the air between a tablet and a WiFi router.

Analog Signal Graphs

Because a signal varies over time, it’s helpful to plot it on a graph where time is plotted on the horizontal, x-axis, and voltage on the vertical, y-axis. Looking at a graph of a signal is usually the easiest way to identify if it’s analog or digital; a time-versus-voltage graph of an analog signal should be smooth and continuous.

While these signals may be limited to a range of maximum and minimum values, there are still an infinite number of possible values within that range. For example, the analog voltage coming out of your wall socket might be clamped between -120V and +120V, but, as you increase the resolution more and more, you discover an infinite number of values that the signal can actually be (like 64.4V, 64.42V, 64.424V, and infinite, increasingly precise values).

Example Analog Signals

Video and audio transmissions are often transferred or recorded using analog signals. The composite video coming out of an old RCA jack, for example, is a coded analog signal usually ranging between 0 and 1.073V. Tiny changes in the signal have a huge effect on the color or location of the video.

An analog signal representing one line of composite video data.

Pure audio signals are also analog. The signal that comes out of a microphone is full of analog frequencies and harmonics, which combine to make beautiful music.

Digital Signals

Digital signals must have a finite set of possible values. The number of values in the set can be anywhere between two and a-very-large-number-that’s-not-infinity. Most commonly digital signals will be one of two values – like either 0V or 5V. Timing graphs of these signals look like square waves.

Or a digital signal might be a discrete representation of an analog waveform. Viewed from afar, the wave function below may seem smooth and analog, but when you look closely there are tiny discrete steps as the signal tries to approximate values:

That’s the big difference between analog and digital waves. Analog waves are smooth and continuous, digital waves are stepping, square, and discrete.

Example Digital Signals

Not all audio and video signals are analog. Standardized signals like HDMI for video (and audio) and MIDI, I2S, or AC'97for audio are all digitally transmitted.

Most communication between integrated circuits is digital. Interfaces like serial, I2C, and SPI all transmit data via a coded sequence of square waves.

Serial peripheral interface (SPI) uses many digital signals to transmit data between devices.

Analog and Digital Circuits

Analog Electronics

Most of the fundamental electronic components – resistors, capacitors, inductors, diodes, transistors, and operational amplifiers – are all inherently analog. Circuits built with a combination of solely these components are usually analog.

Analog circuits are usually complex combinations of op amps, resistors, caps, and other foundational electronic components. This is an example of a class B analog audio amplifier.

Analog circuits can be very elegant designs with many components, or they can be very simple, like two resistors combining to make a voltage divider. In general, though, analog circuits are much more difficult to design than those which accomplish the same task digitally. It takes a special kind of analog circuit wizard to design an analog radio receiver, or an analog battery charger; digital components exist to make those designs much simpler.

Analog circuits are usually much more susceptible to noise (small, undesired variations in voltage). Small changes in the voltage level of an analog signal may produce significant errors when being processed.

Digital Electronics

Digital circuits operate using digital, discrete signals. These circuits are usually made of a combination of transistors and logic gates and, at higher levels, microcontrollers or other computing chips. Most processors, whether they’re big beefy processors in your computer, or tiny little microcontrollers, operate in the digital realm.

Digital circuits make use of components like logic gates, or more complicated digital ICs (usually represented by rectangles with labeled pins extending from them).

Digital circuits usually use a binary scheme for digital signaling. These systems assign two different voltages as two different logic levels – a high voltage (usually 5V, 3.3V, or 1.8V) represents one value and a low voltage (usually 0V) represents the other.

Although digital circuits are generally easier to design, they do tend to be a bit more expensive than an equally tasked analog circuit.

Analog and Digital Combined

It’s not rare to see a mixture of analog and digital components in a circuit. Although microcontrollers are usually digital beasts, they often have internal circuitry which enables them to interface with analog circuitry (analog-to-digital converters, pulse-width modulation, and digital-to-analog converters. An analog-to-digital converter (ADC) allows a microcontroller to connect to an analog sensor (like photocells or temperature sensors), to read in an analog voltage. The less common digital-to-analog converter allows a microcontroller to produce analog voltages, which is handy when it needs to make sound.

Resources and Going Further

Now that you know the difference between analog and digital signals, we’d suggest checking out the Analog to Digital Conversion tutorial. Working with microcontrollers, or really any logic-based electronics, means working in the digital realm most of the time. If you want to sense light, temperature, or interface a microcontroller with a variety of other analog sensors, you’ll need to know how to convert the analog voltage they produce into a digital value.

Also, consider reading our Pulse Width Modulation (PWM) tutorial. PWM is a trick microcontrollers can use to make a digital signal appear to be analog.

Switchgear those who do not know the knowledge

         Switchgear is a complete set of power distribution devices assembled by a device and a secondary device according to a certain scheme, which is mainly used for controlling and protecting circuits and devices. Switchgear according to the voltage level can be divided into high voltage switchgear (fixed and handcart type) and low voltage switchgear (fixed and drawer).

         The structure of high-voltage switchgear is generally similar, mainly divided into bus room, circuit breaker room, secondary control room (instrumentation room), feeder room, the rooms generally have steel isolation.

Internal components include:

         bus (bus), circuit breakers, conventional relays, integrated relay protection , measuring instruments, isolation knife, light, ground knife and so on.

Divided from the application point of view

         1, into the line counters: also known as cabinet, is used to receive power from the grid equipment (from the line to the bus), the general installation of circuit breakers, CT, PT, isolation knife and other components.

         2, outlet cabinet: also known as feeding cabinet or distribution cabinet, is used to distribute power equipment (from the bus to each outlet), generally also installed circuit breakers, CT, PT, isolation knife and other components.

         3, bus cabinets: also known as bus disconnecting cabinet, is used to connect the two bus devices (from the bus to the bus), in a single busbar section, double busbar system often need to use the bus to meet the user to choose different Operating requirements or to ensure that there is a selective fault removal load.

         4, PT cabinet: also called voltage transformer cabinet, usually installed directly to the bus to detect bus voltage and achieve protection. The main installation voltage transformer PT, isolation knife, fuse and arrester.

         5, isolation cabinet: is used to isolate the bus at both ends used or isolated power equipment and power equipment used, it can provide operators with a visible endpoint to facilitate maintenance and repair operations. Since the isolation cabinet does not have the ability to break and turn on the load current, it is not possible to push and pull the handcart of the isolation cabinet when the circuit breaker with which it is closed is closed. In general applications, you need to set the circuit breaker auxiliary contacts and isolation handcart interlock to prevent misoperation of operating personnel.

         6, measuring cabinet: mainly used for measuring electrical energy (kWh), there are high pressure, low pressure of the points, the general installation of isolating switches, fuses, CT, PT, active watt-hour meters , Reactive power meter, relays, and some other secondary equipment (such as load monitors, etc.).

         7, SVG: Static and reactive power generator, the English description is: Static Var Generator, referred to as SVG. Also known as high voltage dynamic reactive power compensation device, or static synchronous compensator. Refers to by the commutation of the power semiconductor bridge converter for dynamic reactive power compensation device. SVG is currently the best solution in the field of reactive power control. SVG has an unparalleled advantage over the traditional tune-up cameras, capacitor reactors and traditional SVC, which is mainly represented by thyristor control reactor TCR.

         8, inflatable switchgear: also known as enclosed combination of electrical cabinet, which is the circuit breakers, disconnectors, earthing switches, CT, PT, arrester, bus and other closed combination of metal housing, and then to the insulation performance and arc performance Good gas (usually sulfur hexafluoride SF6) as a phase and ground insulation measures for high voltage and high capacity level of the grid, as the distribution and control.

From the perspective of components          

         1, circuit breaker: under normal operating conditions, the circuit breaker is closed (except for special applications), connected to the circuit. When automatic control or protection control operation, the circuit breaker in the comprehensive protection device under the control of the circuit breaking or on operation. The circuit breaker can not only cut off the normal load current, but also can withstand the short-circuit current (several times or even several times the normal operating current) for a certain period of time, and can break the short-circuit current and cut off the fault lines and equipment. Therefore, the main function of the circuit breaker is to break and connect the circuit (including breaking and connecting the normal current and breaking the short circuit current). Because of breaking and connecting the circuit in the process, the circuit breaker of the moving contact and the static contact between the inevitable to produce arc. In order to protect the contacts and reduce the loss of contact materials and reliable breaking circuit, measures must be taken to extinguish the arc as soon as possible. One of them is to use different interrupting mediums to fill the circuit breaker's moving and static contacts. According to interrupter medium different circuit breakers can be divided into: oil circuit breakers (oil, less oil), sulfur hexafluoride (SF6) circuit breakers, vacuum circuit breakers, air circuit breakers. The main equipment we have in our high and low voltage switchgear is the circuit breaker. As the circuit breaker, the static contact is generally surrounded by a container filled with interrupter medium, so the circuit breaker points, the state can not be directly judged, usually through the circuit breaker auxiliary devices (such as sub-place pointer Etc.) to determine.

         2, Microcomputer protection device: Microcomputer protection is composed of high integration, the bus is not chip microcontroller, high-precision current and voltage transformers, high dielectric strength outlet intermediate relay, high reliability switching power supply module and other components. Mainly as a computer protection device 110KV and below the voltage level of power plants, substations, distribution stations, etc., can also be used as part of the voltage level between 70V-220V voltage and current protection and monitoring.

         3, isolation knife: isolation knife (or isolation switch) due to obvious fracture can be identified on or off, mainly used to isolate high-voltage power supply, in order to ensure the safety of wiring and equipment maintenance, can break the current is small Usually only a few amps). Because there is no special arc extinguishing device, so it can not be used to break the fault current and normal operating current, does not allow the load with the breaking operation.

         4, Fuse: Fuse is a simple circuit protection appliances, the principle is that when the current flowing through the fuse reaches or exceeds the value of a certain period of time, the melt itself, cut off the circuit. Its action principle is simple, easy to install, generally not used alone, mainly used with other electrical appliances.

         5, load switch: Load switch has a simple arc device, the arc medium generally use air, you can connect and disconnect certain current and over current, but can not break the short circuit current, can not be used to cut off the short circuit fault. So it is absolutely not allowed to simply use the load switch to replace the circuit breaker; if you want to use the load switch, must be used in conjunction with the previously mentioned high-voltage fuses (in fact often use fuses and load switches in series for simple overload protection , In order to reduce the project cost). Load switch similar to the isolation knife, there is a clear gap between the disconnect, you can easily determine the circuit is turned on or off.

         6, PT (TV) / CT (AV) Transformer: Transformer is actually a special transformer, mainly used to electrically isolate the primary circuit and control loop, thereby expanding the secondary equipment (instruments, comprehensive insurance, etc.) The use of. The use of PT / CT can avoid the high voltage / high current of the primary circuit directly entering the secondary control equipment (such as meter, comprehensive protection device, etc.), and also can prevent the primary circuit from running due to the control equipment failure.

         7, handcart: handcart is part of high voltage switchgear, respectively, to install high voltage circuit breakers and other components. Their function is basically the same as that of the fixed switchgear. The main difference is the convenience of maintenance and overhaul (the handcart can be pushed in and out by the mechanical operating mechanism rocker). The handcart generally has three working positions (during normal operation), tests (during commissioning and on-site tests), and exits (during maintenance and overhauls).

         8, ground knife: ground knife (also known as grounding switch) Main: First, used in line and equipment maintenance, in order to ensure the safety of personnel for grounding; Second, it can be used to artificially cause the system ground short circuit, to control The purpose of protection. The first one is well understood and not introduced. The second role is this: Grounding knife is usually connected to the high-voltage side of the step-down transformer, when the receiving end fails or transformer internal failure, ground knife switch should be automatically closed, resulting in short circuit to ground, forcing the power supply side The top) circuit breaker rapid action, cut off the fault, so that this is a personal short circuit to ground fault, the purpose is to ensure that the power supply circuit breakers can quickly move.

         9, instrumentation: Multi-function instrument is developed for low-voltage power monitoring telemetry, remote communications, remote control in one multi-function digital three-phase intelligent measurement and control instruments. It uses high-end configuration, high-performance 32-bit embedded microprocessors, high-precision AD sampling, direct or indirect measurement of three-phase power grid voltage, current, power, power factor and frequency, but also with industrial equipment connected to form control system. Can be widely used in substation automation , distribution automation, residential power monitoring, industrial automation , intelligent building, smart power distribution panels, dashboards, switchboards as the power parameter measurement and control components. Instrument can have RS-485 or TTL communication interface, using Modbus-RTU protocol. According to different requirements, through the instrument panel keys, variable ratio, alarm, communication and other parameters to set and control.

         10, the temperature on-line monitor: handcart type switchgear commonly used in the power supply system, in the high-voltage circuit breaker handcart structure, static contact, moving contact is a basic component in the moving contact with the static contact contact When there is a contact resistance between them, if the contact resistance is too large, the temperature rise will exceed the specified value, thus accelerating the dynamic and static contacts at the contact oxidation, the oxidation result in turn increases the contact resistance, thus contributing to increased fever , The temperature increases, and even arc burn. Contact temperature on-line monitor is developed to avoid such accidents.

         11, intelligent ring counter monitoring: ring counter in the long run, due to a variety of objective causes ring counter in the process of installation and put into operation after the cable lap at the fault, the gas chamber failure, operating mechanism failure, Arrester failure, etc., thus bringing about a hidden danger to the reliable operation of the power grid.

Common switchgear production equipment, including:

         12, sheet metal three pieces: CNC punch, shears, bending machines. These three are the basic tools for sheet metal production, mainly used to make switch cabinet cabinet. Sheet metal processing accuracy of high-pressure handcart-type switchgear, low-voltage drawer-type switchgear greater impact, manifested in the hand truck shake and shake out, drawer interchangeability.

         13, spray equipment: switch cabinet cabinet surface electrostatic spray processing. Electrostatic spray is the use of electrostatic adsorption method to make the powder coating adsorbed on the metal surface after high temperature curing the surface of the protective film formed a full set of processes. Electrostatic spray without thinner, the construction of the environment pollution-free, non-toxic to the human body; coating appearance of excellent quality, adhesion and mechanical strength; spraying construction curing time is short. Spray equipment mainly pickling, degreasing, phosphating, electrostatic spraying, curing and other processes, respectively, using different equipment, the current use of more spray production lines.

         14, busbar processing equipment: busbar processing equipment is mainly used for switchgear cabinet and copper busbar cutting, punching, bending operation, the use of multi-station bus processing machine more.
