X9250TS24IT1

Digital Potentiometers Overview

The X9250TS24IT1 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers on a monolithic CMOS integrated circuit, each featuring 256 resistor taps for 0.4% resolution. The device utilizes an SPI serial interface for wiper position control and includes nonvolatile memory to retain settings. It operates with a single supply voltage ranging from 2.7V to 5.5V or dual supplies up to ±5.5V. The component is housed in a 24-lead SOIC package.

Digital Potentiometers Feature Summary

• Integrates four 100kΩ or 50kΩ digitally controlled potentiometers with 256 taps per channel
• SPI serial interface for digital control of wiper positions
• Nonvolatile data registers store wiper positions for power-up recall
• Low standby current consumption of less than 5µA maximum

Digital Potentiometers Applications

• Control and parameter adjustment circuits
• Signal processing applications requiring variable resistance
• Industrial controls utilizing SPI communication
• Audio volume and tone control systems

Digital Potentiometers Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature range specifications compared to commercial variants. Confirm RoHS compliance status as some datasheets list non-compliance while others indicate compliance depending on manufacturing date. Ensure the 24-SOIC package dimensions match the target PCB footprint requirements before ordering.

Digital Potentiometers Selection Notes

Select this component when four independent variable resistors are required within a single package. The 256-tap resolution provides fine adjustment capabilities suitable for precision applications. Verify that the system interface supports the SPI protocol required for programming the wiper counters and data registers.

Digital Potentiometers Part Context

This part belongs to the X9250 family of Quad Digitally Controlled Potentiometers. It shares core functionality with variants such as the X9250US24T1 and X9250TS24Z, differing primarily in packaging, temperature rating, and specific ordering suffixes defined by the manufacturer.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9250 series variants like the X9250TS24Z or X9250US24T1, provided the package type and electrical characteristics align with the design requirements.
