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 ...

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 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 ...

Industrial controls and variable-bias circuits sometimes require the services of voltage-to-resistance converters. But they can be difficult to implement. The simple approach shown in the figure ...

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