X9401WS24IZ-2.7T1

Digital Potentiometers Overview

The X9401WS24IZ-2.7T1 is a quad digitally controlled potentiometer (XDCP) IC manufactured by Renesas Electronics Corporation, formerly Intersil. It integrates four independent potentiometers on a single monolithic CMOS chip, each featuring 64 tap points and a total resistance of 10 kOhms. The device utilizes a non-volatile memory architecture to retain wiper positions during power loss, recalling the contents of Data Register 0 upon power-up. Communication is managed via a Serial Peripheral Interface (SPI) bus, allowing direct read/write access to volatile Wiper Counter Registers and non-volatile Data Registers. It operates within a supply voltage range of 2.7 V to 5.5 V and is housed in a 24-SOIC surface-mount package.

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 register-oriented control
• Operates on a single 2.7 V to 5.5 V supply

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustments
• Hardware parameter tuning in industrial systems
• Signal processing circuit calibration

Digital Potentiometers Procurement Notes

This component is classified as obsolete and no longer manufactured by Renesas Electronics. Availability is restricted to existing stock or surplus channels. Verification of authenticity and storage history is critical due to the end-of-life status. Designers should consult official replacement guides or cross-reference tools for active alternatives before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this part only if legacy compatibility with the X9401 family is required. Ensure the design supports the 24-SOIC footprint and SPI protocol constraints. Verify that the 10 kOhm resistance value and 64-tap resolution meet the specific application's precision requirements. Check for available direct substitutes such as the X9401WS24IZ-2.7T1 variant if pinout or voltage tolerance differences exist.

Digital Potentiometers Part Context

The X9401 belongs to the XDCP™ series of solid-state potentiometers, designed to replace mechanical pots in applications requiring digital adjustment. It is part of a broader portfolio including single (X9241), dual (X9313), and quad (X9401) configurations. The 'Z' suffix typically indicates lead-free/RoHS compliance, while 'T1' denotes tape-and-reel packaging. This specific model represents an industrial-grade version of the quad-channel device.

Digital Potentiometers Replacement Considerations

Direct substitute part numbers include X9401WS24IZ-2.7T1. Users should verify package dimensions and electrical tolerances against current active components from Renesas or other manufacturers offering equivalent quad digital potentiometers with SPI interfaces.
