X9315UMIT2C7898

Digital Potentiometers Overview

The Intersil X9315UMIT2C7898 is a digitally controlled potentiometer (XDCP) featuring a single resistive element with 32 taps. It operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical operating current of 50 uA. The device utilizes a serial 3-wire interface for wiper position control and includes nonvolatile memory to retain settings without power. Available in an MSOP-8 surface-mount package, it supports linear taper configurations and functions reliably across an extended temperature range from -40°C to +85°C.
