X9401WS24ZT1

Digital Potentiometers Overview

The X9401WS24ZT1 is a quad digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics Corporation. It features four independent circuits, each with 64 taps and a total end-to-end resistance of 10 kOhms. The device utilizes a nonvolatile memory architecture to retain wiper positions without power. Communication is handled via an SPI serial interface. It operates on a single 5V supply and is housed in a 24-SOIC package (0.295 inch width). The component exhibits a linear taper and has a typical contact resistance of 150 Ohms.

Digital Potentiometers Feature Summary

• Quad configuration with 64 taps per circuit
• Nonvolatile EEPROM storage for wiper data retention
• SPI serial interface for control
• 10 kOhm nominal resistance with ±20% tolerance

Digital Potentiometers Applications

• Programmable gain amplifiers

• Voltage reference adjustment
• Sensor calibration and trimming

Digital Potentiometers Procurement Notes

This component is classified as obsolete and no longer in production. Current availability is limited to existing stock or surplus channels. Verification of authenticity and physical condition is critical when sourcing from third-party distributors due to the discontinued status. Supply chain lead times may be extended or unpredictable.

Digital Potentiometers Selection Notes

Designers requiring this specific quad topology should verify pin compatibility with replacement parts such as the X9401WS24IZ-2.7T1. Note that the recommended substitute may differ in voltage range or packaging suffix. Ensure that the target application supports the 5V operating voltage and SPI protocol constraints defined in the original datasheet before substituting.

Digital Potentiometers Part Context

The X9401WS24ZT1 belongs to the X9401 family of digitally controlled potentiometers. It is part of the broader XDCP product line which integrates nonvolatile memory with resistive arrays. This specific variant is distinguished by its quad channel count and SOIC-24 surface-mount packaging, designed for applications requiring multiple adjustable resistance values in a compact form factor.

Digital Potentiometers Replacement Considerations

The X9401WS24IZ-2.7T1 is listed as a direct replacement. Verify electrical specifications and package dimensions match the original design requirements before implementation.
