X93156WM8IZ

Digital Potentiometers Overview

The X93156WM8IZ is a single digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features an Up/Down interface with 32 wiper tap points and nonvolatile memory for position retention. The device offers total resistance values of 12.5kΩ or 50kΩ, operating within a supply voltage range of 2.7V to 5.5V. Key electrical parameters include a typical active current of 200µA at 5V and a maximum standby current of 2µA. It utilizes a solid-state CMOS architecture with temperature-compensated resistive elements and ±25% maximum resistance tolerance.
