X9258US24IZ-2.7T2

Digital Potentiometers Overview

The X9258US24IZ-2.7T2 is a quad digitally controlled potentiometer (XDCP) from Renesas Electronics, part of the XDCP series. It integrates four independent 50 kΩ resistive networks, each featuring 256 taps for precise resistance adjustment. The device utilizes non-volatile memory to retain wiper positions, recalling data from Data Register 0 upon power-up. Communication is managed via an I²C serial interface with optional addressing capabilities. Designed for surface-mount applications in a 24-SOIC package, it operates within a supply voltage range of ±2.7 V to 5.5 V and supports linear taper characteristics.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50 kΩ digital potentiometers
• 256 tap resolution per channel for fine adjustment
• Non-volatile memory retains settings across power cycles
• I²C serial interface with selectable slave address

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference trimming
• Audio volume control circuits
• Sensor bias adjustment

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T2' against official Renesas documentation, as standard listings typically utilize 'T1' or 'Z' suffixes for tape-and-reel or tube packaging. Confirm RoHS3 compliance status and current production lifecycle stage directly with the manufacturer or authorized distributors, as availability may vary by region.

Digital Potentiometers Selection Notes

Select this component when a quad-channel digital potentiometer with non-volatile storage and I²C control is required. Ensure the system voltage falls within the ±2.7 V to 5.5 V range. Verify that the 256-tap resolution and 50 kΩ resistance value align with the circuit's precision and load requirements. Check compatibility with the host controller's I²C bus speed and address configuration.

Digital Potentiometers Part Context

This part belongs to the X9258 family of quad digital potentiometers. Variants such as X9258US24IZ and X9258US24I share similar core specifications but differ in packaging, temperature ranges, and compliance standards. The X9258 series is designed for applications requiring remote programmability of analog parameters without mechanical components.

Digital Potentiometers Replacement Considerations

Direct substitutes include X9258US24IZ and X9258US24IZ-2.7T1. Verify pinout compatibility and electrical parameter alignment before substitution. Cross-reference with X9259 series devices if minor specification adjustments are acceptable.
