X9258US24IT2

Digital Potentiometers Overview

The X9258US24IT2 is a quad digital potentiometer IC from the Renesas XDCP series, housed in a 24-SOIC surface-mount package. It integrates four independent 50 kOhm resistive elements with 256 taps each, controlled via an I²C serial interface. The device features non-volatile memory to retain wiper positions and supports optional slave addressing. Electrical specifications include a supply voltage range of ±2.7V to 5.5V, a typical resistance tolerance of ±20%, and a temperature coefficient of ±300ppm/°C. Contact resistance is typically 150 Ohms.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50 kOhm digital potentiometers
• Non-volatile memory retains wiper settings across power cycles
• I²C serial interface with optional address selection for multi-device systems
• Linear taper characteristic with 256 programmable tap positions

Digital Potentiometers Applications

• Programmable gain amplifiers in signal conditioning circuits
• Digital volume control in audio processing equipment
• Adjustable reference voltage generation in data acquisition systems
• Calibration of sensor bias offsets in industrial instrumentation

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level (MSL 5) requirements for PCB assembly processes. Check for specific ordering suffixes that may indicate packaging variations or environmental certifications.

Digital Potentiometers Selection Notes

Select this component when a quad-channel digital potentiometer with non-volatile storage is required. Ensure the system operates within the ±2.7V to 5.5V supply range. Verify that the I²C bus speed and address configuration are compatible with the host controller. Consider the 24-SOIC package dimensions for layout constraints.

Digital Potentiometers Part Context

This part belongs to the X9258 family of quad digital potentiometers. Variants such as X9258US24IZ and X9258US24Z share similar electrical characteristics but differ in packaging (tube vs. reel) and environmental compliance (RoHS status). The 'T2' suffix typically denotes tape and reel packaging.

Digital Potentiometers Replacement Considerations

Direct replacements include X9258US24IZ and X9258US24Z from Renesas. Verify pinout compatibility and electrical parameter alignment before substitution.
