X9251UV24I

Digital Potentiometers Overview

The X9251UV24I is a quad digital potentiometer IC from the XDCP series, manufactured by Renesas Electronics. It integrates four independent potentiometers, each featuring 256 taps and a resistance of 50 kOhms with linear taper. The device utilizes non-volatile memory to retain wiper settings upon power loss and communicates via an SPI serial interface. It operates within a supply voltage range of 4.5 V to 5.5 V and supports optional addressing for multiple devices on a single bus. The component is housed in a 24-pin TSSOP package.

Digital Potentiometers Feature Summary

• Quad configuration with four independent 50 kOhm digital potentiometers
• Non-volatile memory retains wiper position after power cycle
• SPI serial control interface with optional address selection
• Linear resistance taper with 256 tap positions per channel

Digital Potentiometers Applications

• Programmable gain amplifiers requiring precise resistance adjustment
• Voltage reference trimming in measurement systems
• Audio volume control circuits with digital interface requirements
• Calibration of sensor signal conditioning paths

Digital Potentiometers Procurement Notes

Verify the specific suffix 'UV24I' against official Renesas documentation to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status as it varies by manufacturing date and region. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this component when a quad digital potentiometer with non-volatile storage is required. Ensure the system interface supports SPI communication. Verify that the 50 kOhm resistance value fits the circuit design constraints. Consider the 24-TSSOP package dimensions for PCB layout compatibility.

Digital Potentiometers Part Context

This part belongs to the X9251 family of quad digital potentiometers. Variants differ by resistance value (e.g., 10k, 50k, 100k), interface type (SPI vs I2C), and package style. The UV24I designation specifically indicates the 50k Ohm variant in a TSSOP-24 package with industrial temperature range capabilities.

Digital Potentiometers Replacement Considerations

Direct replacements include other X9251 variants with matching resistance and interface. Cross-reference with Intersil branded parts if sourcing from legacy inventory. Ensure any substitute maintains non-volatile memory functionality and compatible operating voltage ranges.
