X9250UV24I-2.7

Digital Potentiometers Overview

The X9250UV24I-2.7 is a quad digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It integrates four independent 50 kΩ potentiometers, each featuring 256 taps for precise resistance adjustment with 0.4% resolution. The device utilizes a serial SPI interface for control and includes nonvolatile memory to retain wiper positions across power cycles. Designed for surface-mount applications, it operates within an extended industrial temperature range of -40°C to +85°C and is housed in a compact 24-pin TSSOP package.

Digital Potentiometers Feature Summary

• Integrates four independent 50 kΩ potentiometers with 256 discrete tap positions per channel.
• Features nonvolatile data registers that automatically recall the initial wiper position upon power-up.
• Operates on a single supply voltage ranging from 2.7V to 5.5V with low standby current consumption.
• Utilizes a standard 3-wire SPI serial interface for efficient communication and control.

Digital Potentiometers Applications

• Programmable gain amplifiers requiring digital adjustment of signal levels.
• Voltage reference trimming in precision measurement instrumentation.
• Digital volume control circuits in audio processing systems.
• Active filter frequency tuning and parameter adjustment.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +85°C). Confirm the 'U' designation corresponds to the 24-TSSOP package format. Check current production status as this component family may have been superseded by newer iterations or alternative packages.

Digital Potentiometers Selection Notes

Select this model when four independent 50 kΩ resistive paths are required in a single footprint. Ensure the system design supports SPI communication protocols. Verify that the 256-tap resolution meets the application's linearity requirements without necessitating external calibration.

Digital Potentiometers Part Context

This component belongs to the X9250 series of Quad Digitally Controlled Potentiometers. It shares architectural similarities with other members like the X9250US24 but differs in package type and specific electrical ratings. The series is designed to replace mechanical potentiometers in automated manufacturing environments.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements include the X9250US24I-2.7T1 for SOIC packaging variants. For broader compatibility, verify if the X9250TV24I-2.7 serves as a functional equivalent in TSSOP form factors, ensuring interface and voltage specifications align.
