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 circuit exemplifies the thesis that the 555 is to analog timing what the opamp is to analog "everything else"!

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 ...

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 ...

Potentiometers, rheostats, and trimmers are adjustable resistors used to measure or divide voltages in order to protect or control circuits. The terminology surrounding potentiometers and related ...
