Digital potentiometers (pots) offer advantages for audio volume (gain) control applications and can replace bulky mechanical pots, especially in handheld portable devices such as MP3 players, PDAs, ...

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.

Digitally controlled potentiometers are useful for generating analog control voltages under the control of a microcontroller. In some applications, manual pushbutton switches could replace a ...

This design idea details how a standard volume control can be replaced by its solid-state equivalent. Digital potentiometers are often advertised as replacements for rotary volume controls. To ...

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 ...

The DP4 Series digital potentiometer is for ac and dc drive systems needing precise, repeatable speed setting and digital readout. The DP4 supports bipolar connections with power supplies of ±10 Vdc ...
