X9C103S Digital Potentiometer Module

Overview

The X9C103 is a digitally controlled (XDCP) potentiometer. The device consists of a resistor array, wiper switches, a control section, and nonvolatile memory. The wiper position is controlled by a three-wire interface.

The device can be used as a three-terminal potentiometer or as a two-terminal variable resistor in a wide variety of applications ranging from control to signal processing to parameter adjustment.
