A resistor is an electrical device that resists the flow of electrical current. In the digital era, we can find a variety of “digital resistors” for our everyday applications. This article is about ...

Designers and procurement engineers requiring a finely tuned analog output controlled by a digital input have two options: digital potentiometers and digital-to-analog converters (DACs). Both use ...

What are digital potentiometers, and how are they used? Digital potentiometers are integrated circuits that implement a resistive ladder and a digital means of addressing a particular tap on the ...

[Stephen Woodward] is familiar with digital potentiometers but is also familiar with their limitations. That spurred him to create the PWMPot which performs a similar function, but with better ...

In many system applications, it becomes necessary to adjust a switched-mode power supply (SMPS) output voltage within narrow limits in order to remove tolerances and drops in the power path, verify ...

In the last video I demonstrated a Universal Active Filter that I could adjust with a dual-gang potentiometer, here I replace the potentiometer with a processor controlled solid-state potentiometer.

In 2024, Non-Volatile Digital Potentiometers dominated the market with a share of 66.2%, as they can retain any desired resistance setting even during a power loss, making them critical components in ...
