X9241AUS

Digital Potentiometers Overview

The X9241AUS is a quad digital potentiometer IC from the X9241A series, manufactured by Renesas Electronics. It integrates four independent potentiometers, each offering 64 tap positions with a resistance value of 50 kOhms and linear taper characteristics. The device utilizes a non-volatile EEPROM to retain wiper settings upon power loss and communicates via a standard serial 2-wire interface. Designed for surface-mount applications in SOIC-20 packages, it operates on a single 5 V supply within commercial temperature ranges.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50 kOhm digital potentiometers
• Non-volatile memory retains wiper position after power cycle
• Serial 2-wire interface for simplified control connections
• 64-tap resolution with linear taper for precise adjustment

Digital Potentiometers Applications

• Programmable gain amplifiers requiring gain setting adjustments
• Voltage reference trimming in precision measurement circuits
• Audio volume control systems utilizing digital interfaces

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific manufacturing date codes prior to procurement. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package damage during soldering processes.

Digital Potentiometers Selection Notes

Select this model when a quad-channel solution with high resistance values is required. Verify that the 50 kOhm resistance aligns with circuit impedance constraints. Ensure the design accommodates the SOIC-20 footprint and that the serial interface logic levels match the system microcontroller outputs.

Digital Potentiometers Part Context

This component belongs to the X9241A family of CMOS EEPROM digital potentiometers. It shares architectural similarities with variants like the X9241AWSZ but differs in resistance value and package type. The series is characterized by its ability to replace mechanical potentiometers in space-constrained PCB designs.

Digital Potentiometers Replacement Considerations

Direct substitutes include other members of the X9241A family such as the X9241AWSZ, provided the package compatibility and resistance specifications meet the design requirements.
