This is a digitally controllable electronic potentiometer. The heart of the circuit is a 16 channel analog multiplexer. Controlled by the BCD value at the inputs, the output pin of the multiplexer ...

This application note lists a number of application circuits for Intersil’s digitally-controlled (XDCP) potentiometers. The application circuits illustrate the wide variety of possible functions which ...

A new breed of electronically adjustable resistors promises to ease fine-tuning in sensors and other electronic devices. Adjustable resistors have come a long way from mechanical potentiometers set ...

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 ...

A circuit used to control the level of a video signal should have a 3-dB cutoff frequency of greater than 5 MHz for a television application or 100 MHz for a monitor application. CMOS-based digital ...

Straight out of the golden age of DIY electronics, the Digital Wooing Aid circuit turns TTL logic into tender words. It’s ...
