X9251UV24IZ

Digital Potentiometers Overview

The X9251UV24IZ is a quad digitally controlled potentiometer (XDCP) from the Renesas X9251 series, housed in a 24-lead TSSOP package. It integrates four independent potentiometers, each featuring 256 linear taps for precise resistance adjustment. The device utilizes an SPI serial interface for control and includes nonvolatile memory to retain wiper positions. It operates on a single supply voltage ranging from 2.7V to 5.5V, with a typical standby current of less than 5µA. Key electrical parameters include a 100kΩ total resistance option, ±20% tolerance, and a temperature coefficient of ±300ppm/°C.

Digital Potentiometers Feature Summary

• Quad configuration with 256 resistor taps per potentiometer
• SPI serial interface for wiper position control
• Nonvolatile data registers for power-up recall
• Low standby current (< 5µA max)

Digital Potentiometers Applications

• Control and parameter adjustments
• Signal processing circuits
• System calibration

Digital Potentiometers Procurement Notes

Verify the specific suffix 'IZ' against the manufacturer's official documentation to confirm pinout compatibility and RoHS compliance status. Ensure the selected variant matches the required resistance value and package dimensions for the target PCB layout.

Digital Potentiometers Selection Notes

Select this component when a quad digital potentiometer with SPI interface and nonvolatile storage is required. Confirm that the 100kΩ resistance value and 256-tap resolution meet the circuit's precision needs. Verify that the operating voltage range of 2.7V to 5.5V aligns with the system power supply.

Digital Potentiometers Part Context

This part belongs to the X9251 family of quad digitally controlled potentiometers. It shares core features with variants like X9251TS24ZT1 but differs in package type (TSSOP vs SOIC) and potentially environmental ratings. The UV24IZ designation specifies the quad channel, 100kΩ resistance, TSSOP-24 package, and industrial/commercial temperature range options.

Digital Potentiometers Replacement Considerations

Direct substitutes within the same family include X9251TV24IZ for TSSOP packages or X9251US24IZ for SOIC packages, provided the interface and resistance values match. Cross-model replacements require verification of pin compatibility and electrical specifications.
