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 ...

The ISL23328 is a volatile, low voltage, low noise, low power, 128-Tap, dual digitally controlled potentiometer (DCP) with an I2C Bus™ interface. It integrates two DCP cores, wiper switches and ...

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.

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.

The newer a piece of farm equipment, the more likely some aspect of it needs to be calibrated, and sometimes re-calibrated, for it to work correctly. In case. you’ve ever wondered, here’s what ...
