X9400WV24Z-2.7

Digital Potentiometers Overview

The X9400WV24Z-2.7 is a dual digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, part of the X9410 series. It integrates two independent potentiometers, each featuring 64 taps and a resistance value of 10 kOhms with a linear taper. The device utilizes a non-volatile wiper memory to retain settings during power loss and communicates via a Serial Peripheral Interface (SPI). It operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical operating current of 400 uA. The component is housed in a 24-pin TSSOP surface-mount package.

Digital Potentiometers Feature Summary

• Dual-channel architecture with 64-tap resolution per potentiometer
• Non-volatile wiper memory for data retention without power
• SPI serial interface for digital control and configuration
• Linear resistance taper with 10 kOhm nominal value

Digital Potentiometers Applications

• Programmable gain amplifiers requiring precise attenuation
• Digital volume control circuits in audio equipment
• Calibration systems for sensor signal conditioning
• Variable bias voltage generation in analog front-ends

Digital Potentiometers Procurement Notes

This specific part number is listed as End-of-Life (EOL) or discontinued by the manufacturer. Availability is limited to existing stock or surplus markets. Verification of authenticity and storage history is critical due to the component's age and potential moisture sensitivity. Buyers should confirm the exact revision level and packaging condition before procurement.

Digital Potentiometers Selection Notes

Select this component when a dual-channel solution with SPI control and non-volatile memory is required. Ensure the system supports the 2.7 V to 5.5 V supply range and that the 10 kOhm resistance value matches the circuit impedance requirements. Verify that the TSSOP-24 package footprint is compatible with the PCB layout. Consider the 64-tap resolution limit for applications requiring finer adjustment steps.

Digital Potentiometers Part Context

The X9400WV24Z-2.7 belongs to the X9410 family of low-power, solid-state potentiometers. This family replaces mechanical potentiometers in applications where size, reliability, and digital programmability are priorities. The 'Z' suffix typically indicates lead-free compliance, while '-2.7' denotes the minimum operating voltage threshold. It serves as a direct replacement for older Intersil-branded variants in legacy designs.

Digital Potentiometers Replacement Considerations

Direct pin-to-pin replacements may include other X9410 series variants such as the X9410WV24IZ-2.7. Verify interface compatibility and memory type before substitution. Alternative manufacturers offer similar dual-channel SPI digital potentiometers, but parameter matching for resistance tolerance and tap count is essential.
