X9250TS24T1

Digital Potentiometers Overview

The X9250TS24T1 is a digitally controlled potentiometer (XDCP) from the Renesas X9250 series, integrating four independent potentiometers within a single monolithic CMOS integrated circuit. Each potentiometer features 256 resistor taps, providing 0.4% resolution for precise adjustment. The device utilizes a serial peripheral interface (SPI) for control and includes nonvolatile memory to store wiper positions. It operates with supply voltages ranging from 2.7V to 5.5V and is housed in a 24-pin SOIC package.

Digital Potentiometers Feature Summary

• Integrates four independent 100kΩ or 50kΩ digitally controlled potentiometers
• 256 tap positions per potentiometer for high resolution
• SPI serial interface for digital control
• Nonvolatile data registers retain wiper position upon power loss

Digital Potentiometers Applications

• Industrial process control parameter adjustments
• Signal processing gain and offset calibration
• Audio volume and tone control circuits
• Programmable voltage references and biasing

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as datasheets indicate variations between compliant and non-compliant versions within the X9250 family. Confirm the specific resistance value (50kΩ vs 100kΩ) and temperature grade required for the application, as suffixes define these parameters. Check for moisture sensitivity level requirements during storage and handling.

Digital Potentiometers Selection Notes

Select based on required resistance tolerance, typically ±20%, and operating temperature range. Ensure the SPI interface compatibility with the host microcontroller. Consider the standby current consumption, which is less than 5µA, for low-power applications. Verify package availability in SOIC-24 format.

Digital Potentiometers Part Context

The X9250 series represents a family of quad digitally controlled potentiometers designed for replacing mechanical potentiometers in space-constrained designs. The TS24 variant specifically denotes the 24-pin SOIC package configuration. This component allows for remote programming and automated calibration in electronic systems.

Digital Potentiometers Replacement Considerations

Direct replacement options include other X9250 variants with compatible pinouts and electrical characteristics. Verify that substitute parts match the specific resistance value and interface protocol. Cross-reference with Intersil-branded equivalents if sourcing from legacy distributors.
