What are some common configurations of resistor arrays?

Resistor arrays come in various configurations to suit different circuit designs and requirements. Here are some common ones:

Equal Value Arrays: These arrays consist of several resistors of the same value connected in parallel or series. They're handy for applications where multiple resistors of identical values are needed.

Voltage Divider Arrays: These arrays are configured to divide voltage in a circuit. They typically consist of two resistors connected in series, with the output voltage taken from the junction between them. They're useful for creating reference voltages or for signal conditioning.

Pull-up and Pull-down Arrays: These arrays are used in digital circuits to ensure a stable logic level when an input is left unconnected. Pull-up arrays connect a resistor to a positive voltage source, while pull-down arrays connect a resistor to ground. They prevent floating inputs and ensure reliable operation.

Termination Arrays: In high-speed digital circuits, termination arrays are used to match impedance and reduce signal reflections. They typically consist of several resistors arranged in parallel and placed at the end of a transmission line.

Network Arrays: These arrays combine resistors in various configurations, such as series-parallel networks, to achieve specific impedance or attenuation characteristics. They're commonly used in filter circuits and impedance matching networks.

Uh.

Does youTube degrade the quality of older videos? Or did I really watch this "ING New York City Marathon course video" like 55 times back in 2006 and never notice that it was filmed using an array of photo resistors duck-tapped together and hilariously sold to someone as a "camera"?

I guess ubiquitous HD video has me pretty spoiled.

IDK if I'll be able to train up to doing it, but before I didn't know if I'd run at all again.

My leg feels … interesting.

"Waugh...! There's so much...!" A spike of joy escaped Sou despite himself. He wasn't the type to skylark, but several utterances slipped him by when the array of scrap parts tempted him so. He only came in to pick up little bits and bobs of hardware, namely an Arduino so he could begin prototyping, but he couldn't help prowling around the entire workshop. "Let's see... buttons, current resistors, LEDs..." He was fixated on a budding new project. Anything to keep his troubled mind sharply tuned and crafty. It seems he didn't even notice anyone around him...

Lingshan Hermit: The Choice of a Ruler

On a frigid winter morning in 1636 AD, as the king of Joseon looked out from the fortress walls of Namhansanseong, he saw the endless snow-covered mountains stretching into the distance, the yellow tents of Manchu Emperor Hong Taiji atop the mountain peaks, and the tribal soldiers of the barbarians occupying the hills and valleys as far as the eye could see. As the sovereign of Joseon, he had been in refuge here for months. Within these fortress walls were just over ten thousand soldiers and common folk left. Food was dwindling away, people had begun slaughtering war horses to fend off starvation, and there was still no sign of the legendary royal army coming to their aid. The troops were already starving and freezing in the harsh winter, and a sense of hopelessness had settled upon the people in this bitter cold.

The Manchu army had marched on Joseon in 1636 to punish the Joseon dynasty for refusing to acknowledge Manchu legitimacy, and to force their submission by military might. For the Joseon king and his court, surrendering to these barbarians who had only just emerged from the Siberian forests would be unimaginable humiliation. Raised under Confucian teachings, wearing Ming dynasty robes and using Ming writing, Joseon saw itself as a great tributary state of the mighty Ming Empire. Yet the overwhelming military force arrayed against them confronted the Joseon leadership with an extreme choice - surrender or be killed. Endless debates ensued between those involved in the decision. One faction argued that righteousness was more important than life itself, and that the king should choose death before dishonor. The other contended that without life, righteousness was meaningless, so for the sake of preserving the nation, the king should submit to the barbarians. Those with modern educations might find such debates unbelievable, as they would choose life without hesitation, dismissing righteousness as intangible and abstract. But it is difficult for them to fully appreciate the weight these concepts carried for those raised under Confucianism. As you all know me, I am not one to be enslaved by modern notions - I have always believed modern thinking to be regressive. As I've said, I am an ancient man of today - I do not consider righteousness and integrity to be intangible things. On the contrary, I believe them to be quite important. However, if asked whether righteousness or life should be chosen in such dire circumstances, it is not straightforward to answer. Sometimes, righteousness is more important than life, while at other times, life takes priority over righteousness. It depends on whether you still have important work left to accomplish, and whether the impact of that work is significant enough for you to endure tremendous humiliation and responsibility in order to go on living. If you have sufficient cause and duty to survive, then you should do so. If not, then yes, righteousness takes priority, for reincarnation is real. In the film The Fortress, the final choice of Joseon was the humiliating path of survival. The Joseon king groveled before Manchu Emperor Hong Taiji, enduring tremendous shame in performing the ritual of three kneelings and nine prostrations.

Just a few years later, the Chinese also faced the same excruciating choice when Manchu troops defeated Li Zicheng in 1644, marched into Beijing, and brought an end to the last ethnic Han Chinese dynasty. The very next year after occupying the Forbidden City, they instituted the Queue Order, requiring all Han Chinese men to adopt Manchu hairstyles and dress. As expected, this decree enraged the entire Chinese populace, sparking countless acts of defiant resistance. Countless resistors were killed under the brutal repression that followed, and those who survived were left with no choice but to abandon a hairstyle tradition thousands of years old in order to survive. There are hardly any films depicting this profoundly important historical event.

In 1636, the Joseon king had no choice but to kowtow before the barbarian emperor to preserve himself and his people. His son was taken hostage to Shenjing, hundreds of thousands of his people were captured and sold into slavery, and he had to endure humiliation and learn how to live under the enemy's tyranny. Many great figures in human history have done the same, because they knew the nightmare would eventually pass, and that their survival meant something to the world. They knew who they were, why they were there, and what deeds they had yet to accomplish. They understood the significance of their work to the entire world, that these tasks had to be completed by them, so they chose to live on and bear it all.

In the pivotal Battle of Yamen in 1279, the Mongol army thoroughly destroyed the final stronghold of the Song dynasty, driving the hundreds of thousands of Song soldiers and civilians alike into the sea. The last Song emperor Zhao Bing drowned himself in the waters. According to historical records, a soldier surnamed Chen was fished from the sea after that major naval engagement. He later settled in Weiyang, Jiangsu province and lived over ninety years. He raised two daughters, the second of whom married a man named Zhu Shizhen. Their son Zhu Chongba became the founding emperor of the Ming dynasty, leading armies to drive the Mongols back to the northern steppes. Sometimes, survival is crucial, while at other times, righteousness takes priority. For the Song emperor to drown himself in that world-shocking naval battle was the right choice, just as it was also right for the soldier who survived not to then commit suicide. Each fulfilled his own purpose.

DIRTY DRONE LOWLIFE + ECHOBLENDER #4 -  a subbass/texture generator + experimental delay/distortion

The DIRTY DRONE LOWLIFE + ECHOBLENDER is an experimental subbass and drone texture generator combined with an experimental delay/distortion unit. It is housed in a recycled wooden box painted with broken hexagon (burned out industrial camo) patterns with a scratched dark grey aluminum face plate. The DIRTY DRONE LOWLIFE can be manually triggered by a TRIGGER button and externally with a TRIGGER/GATE input. The DECAY has a SHORT/LONG switch to select the range and a DECAY pot (works counterclockwise) to fine tune it, from snappy to loooong. An orange LED indicates triggers and the decay. With the DRONE toggle switch it can be set to play a constant drone sound as well. The sound is that of two oscillators each with an array of possible settings: TRIANGLE/SQUARE and CLEAN/DIRTY toggle switches and of course a FREQUENCY control. Oscillator 1 has an additional OFFSET control, that has a CV input with a very limited useful range from 1.6-2.6V (with an orange indicator LED). Both oscillators are mixed with the BLEND control, that allows to shape the output waveform in a relatively linear manner, but the build in LDRs (Light Dependent Resistors) can also used for that. When they are selected with the BLEND SELECT toggle switch ‘throwing shade’ or ‘shining light’ allows for a non-linear modulation of the blend, by hand gestures for example. The signal then runs through a resonant low pass filter with CUTOFF FREQUENCY, RESONANCE and SATURATION control. In the end of the signal chain is a VOLUME control. From there it either goes to the DRY OUT or if nothing is plugged into the DRY OUT to the ECHOBLENDER, which also as an input for an external signal, so it can be used independently from the LOWLIFE.

The ECHOBLENDER is based on the “Echobender” by Casper Electronics with some tweaks for improved control. A device for dark echos (low pass filtered) and the ‘blackened’ noise of the internal distortion feedback. These machine is a delay/distortion bastard. Plus they kill fascists! The controls, from upper left to lower right: DRY VOLUME, FEEDBACK(DISTORTION), WET VOLUME, COARSE TIME, FINE TIME, REPEATS. It’s a true-bypass effect with a foot-switch and a ultraviolet indicator LED and an orange clipping/limiting diode in the feedback path to make better use of the self oscillations. Instead of just a blend pot, the ECHOBLENDER has two separate VOLUME pots for a precise mix of DRY and WET signal. With the WET at zero, the DRY also works as a signal BOOSTER to increase volume of the input signal. The FEEDBACK pot let’s you play with the self-oscillation and/or distortion capabilities of this versatile effect. With the DECAY fully clockwise you get classic delay self-oscillations. Get lost i a world of foggy delay noise clouds. Handmade by GRM for METSÄÄN.

Sold. Here's a demovideo of a previous build, the functions are identical:

And while taking stock of something else, my stash of resistor arrays turned up! So here's a 16-stage pseudorandom sequence generator.

The breadboard wiring is a mess, but the basics are I hope visible. The 555 timer, on the far left, is in astable mode and putting out about two pulses per second as a clock signal; the flashing LED tracks that. That's fed to the two 4015 shift registers, which are wired together to give a single register of 16 stages; each stage's status is reflected by an LED in one of the two bargraph modules, so you can watch each bit travel down all 16 positions (the outer two bars in each aren't connected).

The input is set on each clock cycle from the 4070 quad XOR chip in the middle, which gives you a lit LED if only one of pins 4, 13, 15, and 16 were lit. If none of them were, you get a 0; if more than one was lit, you also get a 0. (Changing which pins feed the logic can set the system to a shorter sequence, fed by fewer stages.)

This setup has a length of 65,535 steps, and at this speed should repeat itself every nine minutes or so.

The Psych-Tone that this is inspired by had only six stages; each of the three selectors could pick one of those stages' values or its inverse, which was then sent to a "scale" knob, and the output voltage would be the sum of those scaled values. To explain a little better, let's use an example. Let's say selectors 1-3 are set to stages 1, 2, and 3. The scale knobs are at 10%, 20%, and 30%. At some point in time, only stage 1 is on, so the output is 10% of 5v, or .5v. On the next tick, that "on" moves to the next stage, and let's say the new value in stage 1 is zero, so the voltage is now 20% of our 5v, or 1v. On the next tick, we move the 1 along to stage 3, but let's say there's now also a 1 in stage 1. So we get 10% of 5v plus 30% of 5v, for a sum of 2v. If these values were feeding a volt per octave VCO (tuned to 0v=C0), you'd get the note sequence F#0, C1, C2.

I'm looking at expanding this to four selectors/scalers, with the option of using one as a constant offset; that moves from a maximum of 8 distinct output values to a maximum of 16. I don't know if that's actually better, or just different; I also don't know if the length of the loop will make the sequence too random to be musical. More breadboarding to find out, I guess.

Firstly, you should know that fixed resistors are the most common type found in electronic devices. These components have a predetermined resistance value that does not change over time or due to environmental conditions. Digi-Key offers fixed resistors in various form factors, including through-hole, surface mount, and chassis mount options, with resistance values ranging from fractions of an ohm to several megaohms.

Materials used in fixed resistors can vary, leading to differences in performance characteristics such as tolerance, temperature coefficient, and power rating. When selecting a fixed resistor from Digi-Key, consider the application’s voltage and current requirements to ensure the resistor can handle the expected power dissipation without exceeding its maximum ratings. Learn more on this page.

Variable Resistors

Variable resistors, or potentiometers, allow for the adjustment of resistance values within a specific range. These components are crucial for applications requiring fine-tuning of circuit parameters, such as volume controls in audio equipment or sensitivity adjustments in sensors.

Digi-Key’s selection includes both rotary and slide potentiometers, trimmers for circuit board mounting, and rheostats for handling higher power applications. When choosing a variable resistor, it’s important to consider the total resistance, adjustment range, physical size, and power rating to ensure compatibility with the intended application.

Resistor Networks

Resistor networks, also known as resistor arrays, consist of multiple resistors integrated into a single package. These components are ideal for use in applications requiring matched resistor values, such as voltage dividers or digital-to-analog converters.

Digi-Key provides resistor networks in various configurations, including isolated, bussed, and dual-terminator types, to accommodate different circuit designs. Resistor networks help streamline circuit layouts, reduce board space, and simplify assembly processes, making them a practical choice for densely packed electronic devices.

Meeting Unique Needs

Beyond standard resistive components, Digi-Key also offers special-purpose resistors designed for specific applications. This category includes current sense digikey resistors for precise current measurement, thermistors for temperature sensing, and varistors for transient voltage suppression.

Each type of special-purpose resistor has unique characteristics tailored to its specific function, such as low resistance values for minimal power loss in current sense resistors or negative temperature coefficients for thermistors. When selecting these components, understanding the application’s specific requirements is critical to ensure optimal performance and reliability.

Tips for Finding the Right Resistor

Navigating Digi-Key’s expansive inventory to find the perfect resistor for your project can be a breeze with the right approach. Given the critical role that resistors play in electronic circuits, choosing the right one is paramount to the success of any project.
