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 ...

Potentiometers are adjustable components that control voltage in electronic circuits. This video explains how they work and ...

This file type includes high-resolution graphics and schematics when applicable. A common project requirement is to have an adjustable voltage regulator programmed to deliver a specific dc output.

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.

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 ...

Potentiometers allow you to adjust voltage and control signals in electronic circuits. This video explains how they work and why they are used in volume controls, sensors, and many everyday devices. A ...

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 ...
