X9259UV24IT1

Digital Potentiometers Overview

The X9259UV24IT1 is a quad digitally controlled potentiometer (XDCP) from Renesas Electronics, housed in a 24-TSSOP surface-mount package. It integrates four independent potentiometers, each featuring 256 tap points and a linear resistance taper with a nominal value of 50 kOhms. The device utilizes an I2C serial interface for control and includes nonvolatile memory to retain wiper positions during power cycles. Operating within a supply voltage range of 4.5 V to 5.5 V, it supports a maximum operating current of 3 mA and functions reliably across a temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with 256 taps per potentiometer
• Nonvolatile storage for wiper position recall on power-up
• I2C serial interface for write, read, and transfer operations
• Linear resistance taper with 50 kOhm nominal resistance

Digital Potentiometers Applications

• Programming bias voltages in electronic circuits
• Implementation of programmable ladder networks
• Three-resistor programmable network configurations

Digital Potentiometers Procurement Notes

Verify the specific suffix IT1 against official datasheets to confirm tape-and-reel packaging and industrial temperature grade specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for assembly processes. Ensure the 24-TSSOP footprint matches the target PCB design constraints.

Digital Potentiometers Selection Notes

Select this component when a quad digital potentiometer with I2C control and nonvolatile memory is required. The 50 kOhm resistance value and 256-tap resolution suit applications needing precise analog adjustment via digital signals. Verify that the 4.5 V to 5.5 V supply voltage aligns with the system power rails and that the TSSOP-24 package fits the available board space.

Digital Potentiometers Part Context

This part belongs to the X9259 series of quad digitally controlled potentiometers. It shares core architectural features with other variants in the family, such as the X9259TS24IZT1, but differs in package type (TSSOP vs. SOIC) and potentially interface or environmental ratings defined by its specific suffix codes.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9259 series variants like X9259UV24Z if package compatibility allows. Cross-model replacements from the same manufacturer should be evaluated based on matching pinout, resistance values, and interface protocols.
