X9259UV24Z-2.7

Digital Potentiometers Overview

The X9259UV24Z-2.7 is a quad digitally-controlled potentiometer (XDCP) from Renesas Electronics Corporation, housed in a 24-TSSOP package. It integrates four independent potentiometers, each featuring 256 tap points for precise resistance adjustment with 0.4% resolution. The device utilizes an I2C serial interface for control and includes nonvolatile memory to retain wiper positions during power loss. Key electrical parameters include a supply voltage range of 2.7V to 5.5V, a typical wiper resistance of 220Ω, and a temperature coefficient of ±300ppm/°C. It operates within a commercial temperature range of 0°C to 70°C.

Digital Potentiometers Feature Summary

• Quad configuration with 256 taps per potentiometer
• I2C serial control interface
• Nonvolatile storage for wiper position recall on power-up
• Supply voltage range: 2.7V to 5.5V

Digital Potentiometers Applications

• Programmable bias voltage generation
• Ladder network implementation
• Signal processing parameter adjustments

Digital Potentiometers Procurement Notes

Verify the specific suffix '2.7' against the official datasheet to confirm it denotes the minimum operating voltage or a specific variant characteristic, as standard part numbers may vary. Confirm the 24-TSSOP package dimensions and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure compatibility with the I2C bus speed and address settings defined in the technical documentation.

Digital Potentiometers Selection Notes

Select this component when a quad digital potentiometer with I2C interface and nonvolatile memory is required. The 50kΩ resistance value and 256-tap resolution suit applications needing moderate precision. Verify that the 0°C to 70°C operating temperature range meets your environmental constraints, as industrial variants may be available in other packages like SOIC.

Digital Potentiometers Part Context

This part belongs to the X9259 family of quad digitally-controlled potentiometers. It shares core architecture with similar models but differs in interface type (I2C vs. SPI or 2-wire) and package style. The UV24Z suffix indicates the 24-TSSOP package and RoHS compliance. It serves as a solid-state replacement for mechanical potentiometers in systems requiring remote programmability and data retention.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9259 variants with different interfaces or packages, such as X9259US24IZ for SOIC packaging. Cross-reference pinouts and electrical characteristics carefully when replacing with devices from other manufacturers offering I2C digital potentiometers.
