Digital Potentiometers

A digital potentiometer adjusts and trims electronic circuits similar to variable resistors, rheostats and mechanical potentiometers. Sometimes called digital POT, RDAC, or digipot, these compact devices can be used to calibrate system tolerances or dynamically control system parameters. Nonvolatile memory digital potentiometers provide wiper setting retention after a power OFF to ON cycle. In addition, fuse link parts offer a one time program trimmer feature.
