X9251UV24

Digital Potentiometers Overview

The X9251UV24 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers within a single monolithic CMOS integrated circuit, each featuring 256 resistor taps for precise resistance adjustment. The device utilizes a linear taper and communicates via an SPI serial interface. It operates with a supply voltage range of 2.7V to 5.5V and includes nonvolatile memory to retain wiper positions. The component is housed in a 24-lead TSSOP package.

Digital Potentiometers Feature Summary

• Integrates four independent 100kΩ potentiometers with 256 taps each
• SPI serial interface for digital control of wiper position
• Nonvolatile data registers store wiper settings across power cycles
• Operates on a single supply voltage from 2.7V to 5.5V

Digital Potentiometers Applications

• Industrial process control parameter adjustments
• Signal processing gain and offset calibration
• Consumer electronics volume and tone control
• Automotive instrument panel dimming and configuration

Digital Potentiometers Procurement Notes

Verify the specific suffix 'UV24' against official Renesas documentation to confirm the exact resistance value (typically 100kΩ for X9251 series) and package dimensions. Confirm RoHS compliance status and lead-free annealing requirements as these may vary by production batch. Check for end-of-life notices or obsolescence warnings before procurement planning.

Digital Potentiometers Selection Notes

Select this component when four independent variable resistors are required in a compact surface-mount footprint. Ensure the system design supports SPI communication protocols. Verify that the 100kΩ resistance value aligns with the application's impedance requirements. Consider the ±20% tolerance and temperature coefficient if high precision is critical.

Digital Potentiometers Part Context

The X9251UV24 belongs to the XDCP™ family of digitally controlled potentiometers. It is part of a broader lineup that includes variants with different resistance values (e.g., 50kΩ) and packages (SOIC). This specific model represents the quad-channel configuration optimized for applications requiring multiple adjustable parameters without mechanical potentiometers.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9251 series variants such as X9251TS24ZT1 (SOIC package) or X9251TV24I-2.7 (TSSOP package). Verify pin compatibility and electrical specifications before substitution. Cross-reference with X9250 series if dual-supply operation is needed.
