X9259UV24Z

Digital Potentiometers Overview

The X9259UV24Z is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers, each featuring 256 tap positions and a resistance value of 50 kOhms. The device utilizes an I2C serial interface for control and includes non-volatile memory to retain wiper settings. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a linear taper configuration. The component is housed in a 24-TSSOP package with a width of 4.40 mm and is rated for operation between 0°C and 70°C.

Digital Potentiometers Feature Summary

• Quad architecture with four independent 50 kOhm potentiometers
• 256 discrete tap positions per channel for precise adjustment
• Non-volatile data registers preserve wiper settings across power cycles
• I2C serial interface allows connection via two bidirectional lines

Digital Potentiometers Applications

• Signal processing circuits requiring digital gain control
• Parameter adjustments in industrial instrumentation
• Voltage reference trimming in measurement systems

Digital Potentiometers Procurement Notes

Verify the specific suffix 'UV24Z' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Check for recent Product Change Notifications regarding label updates or fabrication site changes. Confirm that the required operating temperature range aligns with the commercial grade specification of 0°C to 70°C.

Digital Potentiometers Selection Notes

Select this component when a quad-channel solution with I2C control is required. Ensure the system design accommodates the 50 kOhm resistance value and the ±20% tolerance. Verify that the PCB layout supports the 24-TSSOP package dimensions and that the I2C bus speed is compatible with the device specifications.

Digital Potentiometers Part Context

This part belongs to the XDCP series of digitally controlled potentiometers from Renesas. It shares functional similarities with other models in the family but differs in interface type and packaging. The UV24Z designation specifically indicates the TSSOP-24 package variant with I2C connectivity, distinguishing it from SPI-based or SOIC-packaged counterparts.

Digital Potentiometers Replacement Considerations

Direct replacements must match the quad configuration, 50 kOhm resistance, and I2C interface. Verify pin-to-pin compatibility if substituting with packages like SOIC-24. Cross-reference with the X9258 or X9259 series variants to ensure equivalent electrical characteristics and memory functionality.
