X9250US24ZT1

Digital Potentiometers Overview

The X9250US24ZT1 is a quad digitally controlled potentiometer (XDCP) from Renesas Electronics, housed in a 24-lead SOIC package. It integrates four independent potentiometers, each featuring 256 taps for 0.4% resolution and a linear taper. The device utilizes nonvolatile memory to store wiper positions, recalling Data Register 0 upon power-up. It operates with a single supply voltage of 2.7V to 5.5V or dual supplies up to ±5.5V. Control is managed via an SPI serial interface, allowing direct access to volatile Wiper Counter Registers and four nonvolatile Data Registers per channel.

Digital Potentiometers Feature Summary

• Quad configuration with 256 taps per potentiometer providing 0.4% resolution
• Nonvolatile storage of wiper position with automatic recall on power-up
• SPI serial interface for control and data register access
• Low standby current of less than 5µA maximum

Digital Potentiometers Applications

• Industrial process control parameter adjustments
• Signal processing circuit tuning
• Programmable gain amplifier settings
• Voltage reference trimming

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as the 'Z' suffix typically indicates lead-free packaging, but confirm against the specific datasheet revision. Check moisture sensitivity level (MSL 5) requirements for handling and storage. Ensure the 24-SOIC footprint matches the target PCB design. Confirm availability as this component may be subject to lifecycle changes.

Digital Potentiometers Selection Notes

Select this part for applications requiring four independent digital pots with nonvolatile memory in a compact SOIC package. Choose between 50kΩ or 100kΩ resistance values based on load requirements; this specific model denotes 50kΩ. Ensure the system supports SPI communication. Consider the ±20% tolerance and ±300ppm/°C temperature coefficient for precision applications.

Digital Potentiometers Part Context

This component belongs to the X9250 family of quad digitally controlled potentiometers. It shares core functionality with variants like the X9250TS24Z (100kΩ) and X9250US24 (non-RoHS). The 'Z' suffix generally signifies RoHS-compliant manufacturing, while 'T1' indicates tape-and-reel packaging for automated assembly.

Digital Potentiometers Replacement Considerations

The X9250US24Z is a verified alternative offering identical electrical specifications with RoHS compliance. For 100kΩ resistance requirements, the X9250TS24Z series serves as a compatible substitute within the same package and feature set.
