X9250UV24

Digital Potentiometers Overview

The X9250UV24 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers within a single monolithic CMOS integrated circuit, housed in a 24-TSSOP package. Each potentiometer features 256 taps for precise resistance adjustment and utilizes nonvolatile memory to retain wiper positions during power loss. The device operates with a supply voltage range of ±5V and employs an SPI serial interface for control. Key electrical parameters include a nominal resistance of 50kΩ, a tolerance of ±20%, and a temperature coefficient of ±300ppm/°C.

Digital Potentiometers Feature Summary

• Quad configuration with 256 resistor taps per potentiometer providing 0.4% resolution
• Nonvolatile data registers store wiper positions for power-up recall
• SPI serial interface for digital control and address selection
• Operates on dual supplies: V+ and VCC from 2.7V to 5.5V, V– from -2.7V to -5.5V

Digital Potentiometers Applications

• Industrial process control parameter adjustments
• Signal processing gain and offset calibration
• Audio volume and tone control circuits
• Programmable filter frequency setting

Digital Potentiometers Procurement Notes

Verify component status as the X9250UV24 is listed as obsolete or discontinued in multiple distributor records. Confirm availability through authorized channels or check for valid replacement alternatives if current production units are required for new designs.

Digital Potentiometers Selection Notes

Select this component when a quad digital potentiometer with nonvolatile storage and SPI interface is required. Ensure the system supports the specified ±5V dual supply rails and that the 50kΩ resistance value aligns with the application's impedance requirements. Verify package compatibility with the 24-TSSOP footprint.

Digital Potentiometers Part Context

The X9250UV24 belongs to the XDCP™ family of digitally controlled potentiometers from Renesas (formerly Intersil). This series is designed to replace mechanical potentiometers in applications requiring remote adjustment, automated calibration, or long-term stability without drift associated with mechanical wear.

Digital Potentiometers Replacement Considerations

Check for direct pin-compatible replacements within the X9250 series, such as variants with different resistance values (e.g., 100kΩ) or packaging options, ensuring they meet the specific voltage and interface requirements.
