X9400YV24IT1

Digital Potentiometers Overview

The X9400YV24IT1 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers, each featuring 64 taps and a total resistance of 2.5 kOhms with linear taper characteristics. The device utilizes non-volatile memory to retain wiper settings upon power loss. Communication is managed via an SPI interface. It operates on a single 5 V supply voltage and is housed in a 24-TSSOP surface-mount package. The component supports optional address selection for multi-device configurations.

Digital Potentiometers Feature Summary

• Quad configuration with 64 taps per potentiometer
• Non-volatile memory retains wiper position after power cycle
• SPI digital interface for control and data transfer
• 2.5 kOhm resistance value with ±20% tolerance

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustment
• Audio volume control circuits
• Sensor biasing and calibration

Digital Potentiometers Procurement Notes

This component is officially marked as obsolete or discontinued by the manufacturer. Verification of availability should focus on surplus distributors or last-time-buy notices rather than standard active inventory channels. Ensure compatibility with existing PCB footprints if sourcing from secondary markets.

Digital Potentiometers Selection Notes

Select this part when a quad-channel digital potentiometer with non-volatile storage and SPI control is required. Verify that the 2.5 kOhm resistance range and 64-tap resolution meet the circuit's precision needs. Confirm that the system design accommodates the 24-TSSOP package dimensions and the specific voltage requirements of the SPI bus.

Digital Potentiometers Part Context
