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 ...

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 ...
