X9221AWPIZ

Digital Potentiometers Overview

The X9221AWPIZ is a dual-channel digital potentiometer IC from the X9221A series, manufactured by Renesas Electronics. It features two independent potentiometers with a resistance value of 10 kOhms and 64 taps per channel. The device utilizes non-volatile memory to retain wiper settings and communicates via a serial 2-wire interface. It operates on a single 5 V supply with a maximum current consumption of 3 mA. The unit is housed in a 20-pin DIP package and supports a linear taper. The operating temperature range extends from -40°C to +85°C.

Digital Potentiometers Procurement Notes

Verify component authenticity due to potential availability issues. Confirm package type matches the 20-pin DIP specification. Check for moisture sensitivity handling requirements during storage and assembly. Ensure compatibility with existing serial interface protocols. Validate that the 10 kOhm resistance meets circuit design constraints.

Digital Potentiometers Selection Notes

Select this model when dual-channel digital adjustment is required with non-volatile memory. The 10 kOhm resistance and 64-tap resolution suit precision analog control applications. The 20-pin DIP package facilitates through-hole mounting. Verify that the 5 V supply voltage aligns with system power rails. Consider the industrial temperature range for harsh environment deployments.

Digital Potentiometers Part Context

The X9221AWPIZ belongs to the X9221A family of digital potentiometers. This series integrates EEPROM technology for persistent setting storage. The component replaces mechanical potentiometers in applications requiring programmable resistance. It offers improved reliability and reduced board space compared to traditional variable resistors.

Digital Potentiometers Replacement Considerations

No verified direct replacement part numbers are available in public documentation. Evaluate alternative digital potentiometer ICs with similar pin counts and interface types. Ensure substitute components match the 10 kOhm resistance and 64-tap specifications. Verify package compatibility if transitioning to surface-mount technologies.
