X9251TS24I-2.7

Digital Potentiometers Overview

The X9251TS24I-2.7 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, housed in a 24-pin SOIC package. It integrates four independent 100kΩ potentiometers, each featuring 256 taps for precise resistance adjustment. The device utilizes an SPI serial interface for control and includes nonvolatile memory to retain wiper positions. Operating within a supply voltage range of 2.7V to 5.5V, it offers linear taper characteristics with ±20% resistance tolerance and a temperature coefficient of ±300ppm/°C. The component supports optional addressing and operates within a commercial temperature range of 0°C to 70°C.

Digital Potentiometers Feature Summary

• Integrates four 100kΩ potentiometers with 256 taps each
• SPI serial control interface with optional address capability
• Nonvolatile data registers for wiper position retention
• Operates on single supply voltages from 2.7V to 5.5V

Digital Potentiometers Applications

• Control and parameter adjustment circuits
• Signal processing applications requiring digital resistance tuning
• System calibration where nonvolatile settings are required

Digital Potentiometers Procurement Notes

This component is identified as discontinued or obsolete in available distributor records. Verification of current availability requires direct consultation with authorized Renesas distributors or the manufacturer. Lead times and minimum order quantities are not applicable due to the end-of-life status. Buyers should confirm the specific suffix 'I' denotes industrial temperature grade variations if applicable, though standard datasheets list commercial ranges for similar variants.

Digital Potentiometers Selection Notes

Select this part when a quad-channel digital potentiometer with SPI interface and nonvolatile storage is required. Ensure the 100kΩ resistance value and 256-tap resolution meet circuit requirements. Verify that the operating environment stays within the 0°C to 70°C range specified for this variant. Consider the ±20% tolerance and contact resistance specifications for precision applications.

Digital Potentiometers Part Context

The X9251 belongs to the XDCP™ family of digitally controlled potentiometers. It shares architectural similarities with the X9250 and X9252 series but differs in interface type and resistance options. The TS24 suffix indicates the 24-lead SOIC plastic package. This model represents a legacy CMOS technology product designed for general-purpose analog control tasks.

Digital Potentiometers Replacement Considerations

As the X9251TS24I-2.7 is discontinued, no direct public substitute part numbers are confirmed. Engineers may need to evaluate newer generations of digital potentiometers from Renesas or other manufacturers, ensuring compatibility with SPI interfaces and nonvolatile memory requirements.
