This Design Idea describes an analog voltage that controls a digital potentiometer through the device’s I 2 C interface. An ADC in the Microchip PIC12F683 microcontroller converts the analog voltage ...

NORWOOD, Mass.--(BUSINESS WIRE)-- Analog Devices, Inc. (ADI) today introduced a series of non-volatile single-, dual- and quad-channel digital potentiometers (digiPOTs) thatimprove component matching ...

A potentiometer is a three-terminal resistor with a rotating (as in this instrument) or sliding contact that forms an adjustable voltage divider. This example has a front bearing plate of gold-colored ...

This application note compares digital to analog converters (DACs) to digital potentiometers. Traditionally digital potentiometers were meant to replace simple mechanical pots. With recent increases ...

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 ...

While the “M” in MIDI stands for “musical”, it’s possible to use this standard for other things as well. [s-ol] has been working on a VJ setup (mixing video instead of music) using various ...

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.
