X9221AYPI

Digital Potentiometers Overview

The X9221AYPI is a dual-channel digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates two independent potentiometers, each offering 64 resistive taps with a total resistance of 2 kOhms and a linear taper. The device utilizes an I2C serial interface for communication and features nonvolatile memory to retain wiper positions during power cycles. Operating on a single 5V supply, it functions within a temperature range of -40°C to +85°C. The component is housed in a 20-pin plastic dual in-line package (PDIP) designed for through-hole mounting.

Digital Potentiometers Feature Summary

• Dual channel configuration with 64 taps per potentiometer
• I2C serial interface for digital control
• Nonvolatile storage of wiper position data
• Linear resistance taper with 2 kOhm nominal value

Digital Potentiometers Applications

• Signal processing parameter adjustments
• Control circuit calibration
• Variable resistor implementations in instrumentation

Digital Potentiometers Part Context

This component belongs to the X9221A series of digitally controlled potentiometers. It is distinct from other variants such as the X9221AWSIZ, which uses a SOIC-20 surface-mount package and a 2-wire serial interface instead of I2C. The X9221AYPI specifically denotes the PDIP package and I2C compatibility within this product family.
