X9250US24-2.7

Digital Potentiometers Overview

The X9250US24-2.7 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation, housed in a 24-pin SOIC package. It integrates four independent potentiometers, each featuring 256 taps for 0.4% resolution and a linear resistance taper. The device utilizes an SPI serial interface for wiper position control and includes nonvolatile memory to retain settings across power cycles. Electrical specifications include a supply voltage range of 2.7V to 5.5V, a typical wiper resistance of 40Ω at VCC=5V, and a standby current of less than 5µA. The component supports dual supplies ranging from -2.7V to 5.5V.

Digital Potentiometers Feature Summary

• Integrates four 50kΩ potentiometers with 256 taps per channel
• SPI serial interface for digital control of wiper positions
• Nonvolatile data registers (DR0-DR3) store wiper positions
• Low standby current consumption (< 5µA max)

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

Verify the RoHS compliance status carefully, as documentation indicates conflicting information regarding lead-free certification for this specific part number. Confirm the manufacturing status, as sources indicate the X9250US24 series may be obsolete or end-of-life. Ensure the selected variant matches the required operating temperature range and package dimensions before procurement.

Digital Potentiometers Selection Notes

Select this component when four independent, digitally adjustable resistors are needed within a single package. The 50kΩ resistance value and 256-tap resolution suit precision adjustment tasks. Verify compatibility with the system's SPI bus voltage levels and ensure the 24-SOIC footprint fits the PCB layout constraints. Consider the ±20% tolerance if precise absolute resistance values are critical.

Digital Potentiometers Part Context

This component belongs to the XDCP™ family of digitally controlled potentiometers. It serves as a monolithic CMOS integration of four potentiometers, replacing mechanical pots in applications requiring remote or automated adjustment. The US24 suffix denotes the 50kΩ resistance option in the 24-lead SOIC package.

Digital Potentiometers Replacement Considerations

The X9250US24Z is listed as a potential substitute part number. Verify pinout compatibility and electrical specifications against the original datasheet before substitution.
