Digital Controlled Potentiometers (DCPs)

Renesas offers the widest selection of low-to-high resolution digital potentiometers (DCPs) in single, dual, and quad configurations that are accurate, easy to adjust, and reduce manufacturing complexity.

Available in both linear and non-linear tapers, these digital potentiometers replace mechanical potentiometers and trim resistors in applications where digital control allows microprocessor interfacing and extended functionality. Compared to mechanical potentiometers, electronic potentiometers are more accurate, easier to adjust, and reduce manufacturing complexity.
