X9259UV24IZT1

Digital Potentiometers Overview

The X9259UV24IZT1 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent 50kΩ potentiometers, each featuring 256 taps for linear resistance adjustment. The device utilizes an I²C serial interface for communication and includes nonvolatile memory to retain wiper positions during power loss. It operates within a supply voltage range of 2.7V to 5.5V and is housed in a 24-lead TSSOP package with a specified operating temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50kΩ potentiometers
• 256-tap resolution per channel for precise control
• Nonvolatile data registers store wiper positions
• I²C serial interface for digital control

Digital Potentiometers Applications

• Audio volume and tone control circuits
• Programmable gain amplifier adjustments
• Voltage reference trimming
• System calibration and parameter setting

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors. Confirm the specific suffix 'IZT1' against official datasheets to ensure correct packaging and tape-and-reel specifications. Check for end-of-life status or obsolescence notices from Renesas prior to procurement planning.

Digital Potentiometers Selection Notes

Select this model when a quad-channel digital potentiometer with I²C interface is required. Ensure the 50kΩ resistance value and 256-tap resolution meet circuit requirements. Verify that the system logic levels are compatible with the I²C interface and that the 24-TSSOP package fits the PCB layout constraints.

Digital Potentiometers Part Context

This component belongs to the X9259 series of quad digitally controlled potentiometers. It shares core functionality with variants such as X9259UV24IZ and X9259US24IT1, differing primarily in packaging type (TSSOP vs. SOIC) and reel specifications. The series is designed for applications requiring adjustable resistance without mechanical potentiometers.

Digital Potentiometers Replacement Considerations

Direct substitutes include X9259UV24IZ and X9259US24IT1. Verify pin compatibility and electrical parameters before substitution. Note that package differences may require PCB redesign.
