X9251TS24T1

Digital Potentiometers Overview

The X9251TS24T1 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent potentiometers within a single monolithic CMOS integrated circuit, housed in a 24-pin SOIC package. Each potentiometer features 256 taps with a total resistance of 100 kOhms and linear taper characteristics. The device operates on a supply voltage ranging from 2.7V to 5.5V and utilizes an SPI serial interface for control. It includes nonvolatile memory to retain wiper positions during power loss.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 100 kOhm potentiometers
• 256 tap resolution per potentiometer with linear taper
• SPI serial interface for digital control
• Nonvolatile data registers for wiper position retention

Digital Potentiometers Applications

• Industrial control parameter adjustments
• Signal processing circuit tuning
• System calibration and offset trimming

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'T1' corresponds to tape and reel packaging requirements. Check current product status as legacy components may have limited availability or end-of-life implications.

Digital Potentiometers Selection Notes

Select this component when four isolated 100 kOhm digital pots are required in a compact surface-mount package. Ensure the system supports SPI communication protocols. Verify that the 2.7V to 5.5V operating voltage range aligns with the target application's power supply constraints.

Digital Potentiometers Part Context

This part belongs to the X9251 series of low noise, low power digitally controlled potentiometers. It is functionally similar to the X9250 but typically specified for single-supply operation without negative voltage rails. The TS24 designation indicates the 24-lead SOIC physical package format.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9251 variants with different packages such as X9251TV24 (TSSOP). Cross-model substitutes like the X9250US24T1 offer similar functionality but may require dual-supply voltage considerations.
