X9258US24IZ-2.7T1

Digital Potentiometers Overview

The X9258US24IZ-2.7T1 is a quad digital potentiometer from the Renesas XDCP series, housed in a 24-SOIC surface-mount package. It integrates four independent 50 kΩ resistive networks, each providing 256 adjustable taps with linear taper characteristics. The device operates on a supply voltage range of ±2.7 V to 5.5 V and features nonvolatile memory for wiper position retention. Communication is managed via an I²C interface with optional address selection capabilities. The component maintains a typical contact resistance of 40 Ω and exhibits a temperature coefficient of ±300 ppm/°C across its operating range.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50 kΩ, 256-tap digital potentiometers
• Nonvolatile memory retains wiper settings after power loss
• I²C serial control interface with selectable slave addresses
• Linear resistance taper and ±20% resistance tolerance

Digital Potentiometers Applications

• Precision signal conditioning and gain adjustment circuits
• Programmable filter frequency tuning
• System calibration and parameter trimming
• Audio volume and tone control systems

Digital Potentiometers Procurement Notes

Verify manufacturing status as this specific suffix combination may indicate end-of-life or obsolete inventory. Confirm RoHS compliance and moisture sensitivity level (MSL) ratings prior to procurement. Ensure the I²C address configuration matches system requirements. Check for valid replacement options if current stock availability is limited or discontinued.

Digital Potentiometers Selection Notes

Select this component when a quad digital potentiometer with nonvolatile storage and I²C control is required. The 50 kΩ resistance value suits moderate impedance applications. Verify that the ±2.7 V minimum supply voltage aligns with the system power rails. Consider the 24-SOIC footprint constraints during PCB layout design.

Digital Potentiometers Part Context

This part belongs to the X9258 family of digitally controlled potentiometers. Variants differ by package type (SOIC vs TSSOP), temperature grade (Industrial vs Extended), and supply voltage range (standard vs low-voltage). The 'IZ' suffix typically denotes industrial temperature range and RoHS compliance, while 'T1' indicates tape and reel packaging.

Digital Potentiometers Replacement Considerations

X9258US24IZ is a direct pin-compatible alternative without the tape-and-reel suffix.
