X9271UV14IT1

Digital Potentiometers Overview

The X9271UV14IT1 is a single-channel digital potentiometer IC from the X9271 series, manufactured by Renesas Electronics. It features a resistance value of 50 kOhms with 256 taps and utilizes a linear taper profile. The device operates via a Serial Peripheral Interface (SPI) and includes non-volatile memory to retain wiper settings. It supports a supply voltage range of 4.5 V to 5.5 V, with a typical operating current of 400 uA. The component is housed in a 14-TSSOP surface-mount package and is rated for an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Single digital potentiometer configuration with 50 kOhm total resistance and 256 adjustable taps.
• Non-volatile memory storage retains wiper position data upon power loss.
• SPI serial interface allows for compact system design and easy integration.
• Linear taper characteristic provides uniform resistance adjustment across the tap range.

Digital Potentiometers Applications

• Industrial process control systems requiring precise analog signal adjustment.
• Audio equipment for volume or tone control applications.
• Test and measurement instruments needing programmable gain or attenuation.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'IT1' against official Renesas documentation to confirm tape-and-reel packaging and extended temperature ratings. Confirm end-of-life status as variants within this family may have different lifecycle statuses. Ensure compatibility with existing SPI bus protocols before procurement.

Digital Potentiometers Selection Notes

Select this model over the UV14IZ variant if operation below 0°C is required, as the 'U' indicates an extended temperature range. Choose the IT1 suffix specifically for reel-based manufacturing processes rather than tube packaging. Verify that the 50 kOhm resistance value aligns with the target circuit's impedance requirements compared to other available values like 10 kOhm or 100 kOhm.

Digital Potentiometers Part Context

This component belongs to the X9271 family of single-channel digital potentiometers. It shares architectural similarities with parts like the X9271TV14IZ but differs in resistance value, temperature rating, and packaging format. The X9271 series is designed to replace mechanical potentiometers in space-constrained applications where non-volatile adjustment is necessary.

Digital Potentiometers Replacement Considerations

Direct pin-compatible replacements include the X9271UV14IZ for tube-packaged units or the X9271TV14IZ for similar temperature ranges. Check for updated revisions from Renesas that may offer improved availability while maintaining electrical specifications.
