X9221AWS

Digital Potentiometers Overview

The X9221AWS is a dual-channel digitally controlled potentiometer IC from the XDCP series, manufactured by Renesas Electronics. It features two independent potentiometers with a resistance value of 10 kOhms and 64 tap positions per channel. The device utilizes non-volatile memory to retain wiper settings and communicates via a 2-wire serial interface. It operates on a single 5V supply with a maximum voltage of 5.5V and minimum of 4.5V, drawing approximately 3mA. The component is housed in a 20-SOIC package, supports linear taper, and functions within an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Dual-channel configuration with 10 kOhm resistance and 64 taps per potentiometer
• Non-volatile EEPROM storage retains wiper position after power loss
• 2-wire serial control interface for simplified connectivity
• Industrial temperature rating from -40°C to +85°C

Digital Potentiometers Applications

• Programmable gain amplifiers requiring precise resistance adjustment
• Voltage reference trimming in signal conditioning circuits
• Digital volume control in audio processing systems

Digital Potentiometers Procurement Notes

The X9221AWSIZ variant is listed as End-of-Life (EOL) by the manufacturer. Verification of current availability through authorized distributors or secondary market suppliers is required before procurement planning. Check for specific RoHS compliance details and moisture sensitivity levels relevant to assembly processes.

Digital Potentiometers Selection Notes

Select this component when a dual-channel digital potentiometer with non-volatile memory is needed. Ensure the design accommodates the 20-SOIC package dimensions and the 10 kOhm resistance value. Verify that the system power supply remains within the 4.5V to 5.5V range and that the 2-wire serial interface matches the host controller's capabilities.

Digital Potentiometers Part Context

This part belongs to the X9221A family of digital potentiometers. Variants such as X9221AYSI indicate different resistance values (e.g., 2 kOhm) while maintaining the same package and interface. The AWS suffix typically denotes specific packaging or environmental compliance attributes within the product line.

Digital Potentiometers Replacement Considerations

The CAT5221WI-10-T1 from onsemi is identified as a similar replacement option. Verify pin compatibility and electrical specifications against the original datasheet before substitution.
