X9259US24Z-2.7

Digital Potentiometers Overview

The X9259US24Z-2.7 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers, each featuring 256 taps and a linear resistance taper. The device utilizes a 2-wire serial interface for control and includes nonvolatile memory to retain wiper positions. Electrical specifications include a supply voltage range of 2.7V to 5.5V, a typical wiper resistance of 150Ω, and a temperature coefficient of ±300ppm/°C. The component is housed in a 24-pin SOIC package.

Digital Potentiometers Feature Summary

• Quad configuration with 256 resistor taps per potentiometer
• Nonvolatile data registers for persistent wiper position storage
• 2-wire serial control interface
• Supply voltage range from 2.7V to 5.5V

Digital Potentiometers Applications

• Control and parameter adjustment circuits
• Signal processing applications requiring variable resistance
• System calibration where power-down retention is required

Digital Potentiometers Procurement Notes

Verify the specific suffix 'Z-2.7' against official Renesas documentation to confirm voltage range and compliance status. Confirm package type as 24-SOIC and check current production status, as variants within this family may have different availability or end-of-life statuses.

Digital Potentiometers Selection Notes

Select this component when a quad digital potentiometer with nonvolatile memory and a 2-wire interface is required. Ensure the system operates within the 2.7V to 5.5V supply range. Verify that the 150Ω typical wiper resistance and ±20% tolerance meet circuit requirements compared to other X925x series options.

Digital Potentiometers Part Context

This part belongs to the X9259 family of quad digitally controlled potentiometers. It shares architectural similarities with the X9258 and X9250 but differs in interface type and specific electrical characteristics. The US24 designation indicates the 24-lead SOIC package variant.

Digital Potentiometers Replacement Considerations

Cross-reference with other X9259 variants such as X9259TS24Z-2.7 for pin-compatible alternatives. Verify interface compatibility and resistance values before substituting.
