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 ...

A resistor is characterized by an always constant resistive value. With the same applied voltage, it will always pass the same amount of current. The potentiometer, on the other hand, is an electronic ...

Download the full article as a .PDF, sponsored by Analog What are digital potentiometers, and how are they used? Digital potentiometers are integrated circuits that implement a resistive ladder and a ...

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 ...

Digital potentiometers are resistive elements that are controlled by digital codes. They differ from their analog counterparts in that they are silicon-based rather than mechanical devices. Instead of ...
