X9C104ST2

Overview

The X9C104ST2 is a digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics, belonging to the X9C10 series. It features a single channel with a total resistance of 100 kΩ and a linear taper. The device utilizes a 3-wire serial interface for control and contains 100 tap positions. Its wiper position is stored in non-volatile memory, allowing recall upon power-up. Operating on a single 5V supply, it is housed in an 8-pin SOIC package.

Feature Summary

• Non-volatile memory retains wiper position data without external power
• 100 resistive elements provide precise digital adjustment
• Linear resistance taper ensures uniform voltage division
• CMOS technology supports low power consumption

Applications

• Signal processing parameter adjustment
• Control system gain setting
• Audio volume control circuits

Part Context

The X9C104ST2 is part of the broader X9C10 family, which includes variants like X9C102, X9C103, and X9C104. These devices share the same control interface and memory architecture but differ in total resistance values. The ST2 suffix typically denotes specific packaging or tape-and-reel configurations within the product line.
