X9241AUSIZ

Digital Potentiometers Overview

The X9241AUSIZ is a quad digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics. It integrates four independent 50 kOhm resistive elements, each providing 64 tap positions for precise resistance adjustment. The device utilizes non-volatile memory to retain wiper settings upon power loss and communicates via a standard I2C serial interface. Operating on a single 5V supply with a maximum voltage of 5.5V, it features linear taper characteristics and operates within an industrial temperature range of -40°C to +85°C. The component is housed in a 20-lead SOIC surface-mount package.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50 kOhm digital potentiometers

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing date codes against current project requirements. Check for end-of-life notices or production change notifications that may affect long-term supply stability.

Digital Potentiometers Selection Notes

Select this model when four isolated digital pots are required in a compact SOIC footprint. Ensure the system supports I2C communication protocols and operates within the 4.5V to 5.5V supply range. Verify that the 50 kOhm resistance value and 64-step resolution meet the circuit's precision needs compared to other available resistance values in the X9241A family.

Digital Potentiometers Part Context

The X9241AUSIZ belongs to the X9241A family of CMOS electrically erasable programmable potentiometers. This series combines the functionality of traditional mechanical potentiometers with digital control interfaces. The 'U' suffix indicates the SOIC-20 package type, while 'SIZ' typically denotes specific commercial/industrial grade variations and packaging configurations within the Renesas portfolio.

Digital Potentiometers Replacement Considerations

Direct replacements include X9241AUPIZ (PDIP-20 package) and X9241AWSIZT1 (SOIC-20 tape & reel). Verify pin compatibility and package dimensions before substitution. Alternative packages such as TSSOP-20 (X9241AUVIZ) require careful layout review due to different physical footprints.
