X9401WS24Z-2.7T1

Digital Potentiometers Overview

The X9401WS24Z-2.7T1 is a quad digitally controlled potentiometer (XDCP) IC manufactured by Renesas Electronics Corporation, part of the XDCP series. It integrates four independent potentiometers within a single monolithic CMOS circuit, each featuring 64 tap points and a total resistance of 10 kOhms. The device utilizes a non-volatile memory architecture to retain wiper positions, allowing for power-up recall via an SPI serial interface. Designed for surface-mount applications in a 24-SOIC package, it operates on a supply voltage ranging from 2.7 V to 5.5 V with a typical operating current of 400 uA.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 10 kOhm potentiometers
• Non-volatile memory retains wiper settings across power cycles
• SPI serial interface for digital control and data access
• Wide supply voltage range from 2.7 V to 5.5 V

Digital Potentiometers Applications

• Control and parameter adjustment circuits
• Signal processing systems requiring programmable resistance
• Industrial equipment needing reliable analog signal tuning

Digital Potentiometers Procurement Notes

This component is listed as obsolete or end-of-life by the manufacturer. Verification of availability should focus on distributor surplus stock or secondary market sources rather than direct manufacturing orders. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to procurement to ensure handling requirements are met.

Digital Potentiometers Selection Notes

Select this part when a quad-channel digital potentiometer with non-volatile storage is required. Ensure the application supports SPI communication and operates within the 2.7 V to 5.5 V voltage range. Verify that the 10 kOhm resistance value and 64-tap resolution meet the specific circuit precision needs.

Digital Potentiometers Part Context

The X9401 belongs to the X9400 family of quad digitally controlled potentiometers. It shares architectural similarities with other members like the X9400 but differs in specific pinout configurations and electrical tolerances. This series is designed for replacing mechanical potentiometers in space-constrained PCB designs.

Digital Potentiometers Replacement Considerations

Direct substitutes include the X9401WS24IZ-2.7T1. Verify pin compatibility and electrical specifications before substitution.
