X9258US24ZT2

Digital Potentiometers Overview

The X9258US24ZT2 is a quad digitally controlled potentiometer (XDCP) IC from Renesas Electronics, housed in a 24-lead SOIC package. It integrates four independent 50 kOhm resistive networks, each providing 256 tap points for linear adjustment. The device utilizes a nonvolatile memory architecture to retain wiper positions, recalling them automatically upon power-up. Communication is managed via a standard two-wire serial interface (I²C). Operating within a supply voltage range of 4.5 V to 5.5 V, the component draws a maximum standby current of 100 µA and supports an operating temperature range from 0°C to +70°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50 kOhm potentiometers
• 256 discrete tap points per channel for precise resistance control
• Nonvolatile data registers store wiper positions for power-on recall
• Two-wire serial I²C interface for write, read, and transfer operations

Digital Potentiometers Applications

• Programmable bias voltage generation in analog circuits
• Implementation of programmable ladder networks
• Signal processing parameter adjustments
• Three-resistor programmable network configurations

Digital Potentiometers Procurement Notes

Verify RoHS compliance status through official datasheets, as historical variants may differ. Confirm moisture sensitivity level (MSL 5) requirements for PCB assembly processes. Ensure the specific suffix 'T2' corresponds to the reel packaging format intended for surface mount technology production lines.

Digital Potentiometers Selection Notes

Select this model when a quad-channel digital potentiometer with nonvolatile storage is required. The 50 kOhm resistance value and linear taper are fixed specifications. Verify that the system operates within the 4.5 V to 5.5 V supply range and that the I²C bus timing aligns with the device's serial interface capabilities.

Digital Potentiometers Part Context

This component belongs to the X9258 series of XDCP™ devices. It shares core architectural features with other members like the X9258US24Z, differing primarily in packaging quantity and suffix designation. The series is designed for applications requiring solid-state replacement for mechanical potentiometers with adjustable settings.

Digital Potentiometers Replacement Considerations

The X9258US24Z is listed as a direct substitute. Verify pinout compatibility and electrical parameters before substitution. Note that the base part number X9258US24 is marked as obsolete in some distributor records.
