X9251TS24IT1

Digital Potentiometers Overview

The X9251TS24IT1 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers within a single monolithic CMOS integrated circuit, each featuring 256 resistive taps for precise adjustment. The device utilizes a linear taper and operates via an SPI serial interface. It supports a supply voltage range of 2.7V to 5.5V and includes nonvolatile memory to retain wiper positions. The component is housed in a 24-lead SOIC package with an industrial operating temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 100kΩ or 50kΩ potentiometers per package
• 256-tap resolution providing 0.4% precision control
• SPI serial interface for digital control and data transfer
• Nonvolatile storage retains wiper position during power loss

Digital Potentiometers Applications

• Industrial process control parameter adjustments
• Signal processing gain and offset calibration
• Audio volume and tone control circuits
• Programmable filter frequency setting

Digital Potentiometers Procurement Notes

Verify the specific resistance value (50kΩ vs 100kΩ) as datasheets may vary by revision. Confirm RoHS compliance status, as earlier versions were non-compliant while later revisions meet ROHS3 standards. Check for obsolescence notices from Renesas, as some variants in this series have been discontinued.

Digital Potentiometers Selection Notes

Select this component when multiple independent analog resistance adjustments are required in a compact form factor. Ensure the system design accommodates the SPI communication lines. Verify that the 256-step resolution meets the application's precision requirements compared to lower-resolution alternatives.

Digital Potentiometers Part Context

This part belongs to the X9250/X9251 family of Quad Digitally Controlled Potentiometers. The X9251 variant typically supports dual-supply operation, allowing for negative voltage handling compared to the single-supply X9250. The 'TS24' suffix indicates the 24-lead SOIC package type.

Digital Potentiometers Replacement Considerations

Direct replacements include the X9250TS24Z for single-supply applications. For dual-supply needs, verify compatibility with other X9251 variants such as X9251US24IT1 or X9251TV24I-2.7 depending on package and temperature requirements.
