X9221AWSIZT1

Digital Potentiometers Overview

The X9221AWSIZT1 is a dual-channel digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics. It features two independent potentiometers with a resistance value of 10 kOhms and 64 taps each. 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 component is housed in a 20-SOIC surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Digital Potentiometers Feature Summary

• Dual-channel configuration with 10 kOhm linear taper resistors
• Non-volatile memory for persistent wiper position storage
• Serial 2-wire (I2C-compatible) digital control interface
• Industrial temperature range operation (-40°C to +85°C)

Digital Potentiometers Applications

• Audio volume and tone control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming
• Sensor calibration systems

Digital Potentiometers Procurement Notes

Verify availability status as this part number may be subject to end-of-life or discontinuation notices. Confirm that the 'T1' suffix denotes tape-and-reel packaging if required for automated assembly, distinct from tube-packaged variants. Check for moisture sensitivity level (MSL 3) handling requirements during storage and reflow soldering processes.

Digital Potentiometers Selection Notes

Select this component when a dual-channel solution is required to save board space compared to single-channel alternatives. Ensure the 10 kOhm resistance value and 64-step resolution meet the circuit's precision requirements. Verify that the system voltage aligns with the 4.5 V to 5.5 V operating range and that the I2C interface is compatible with the host microcontroller.

Digital Potentiometers Part Context

This device belongs to the X9221A family of EEPROM-based digital potentiometers. It shares functional similarities with other members like the X9221AWSIZ but differs in packaging format. The T1 suffix typically indicates reel packaging for high-volume surface-mount production, whereas the Z suffix often denotes tube packaging.

Digital Potentiometers Replacement Considerations

The CAT5221WI-10-T1 from onsemi is listed as a similar replacement option. Verify pin compatibility and electrical specifications before substitution. Other X9221 variants may serve as direct replacements if packaging differences are accommodated.
