X9271TV14-2.7

Digital Potentiometers Overview

The X9271TV14-2.7 is a single-channel non-volatile digital potentiometer from the XDCP series, manufactured by Renesas Electronics Corporation. It features a total resistance of 100 kOhms with a linear taper and 256 tap positions for precise adjustment. The device operates on a supply voltage range of 2.7V to 5.5V and utilizes an SPI serial interface for control. Packaged in a 14-TSSOP surface-mount case, it supports an industrial operating temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Non-volatile memory retains wiper position upon power loss
• 256-tap resolution with 100 kOhm total resistance
• SPI serial interface for digital control
• Wide supply voltage range: 2.7V to 5.5V

Digital Potentiometers Applications

• Industrial process control systems requiring adjustable gain or reference voltages
• Consumer electronics calibration circuits
• Audio equipment volume or tone control interfaces

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeits. Confirm RoHS compliance status as specifications vary by manufacturing date. Check for obsolescence notices or last-time-buy deadlines, as this part number may be discontinued or subject to phase-out changes.

Digital Potentiometers Selection Notes

Select this model when high resistance values (100 kOhm) and fine 256-step resolution are required. Ensure the application environment stays within the -40°C to +85°C temperature range. Verify that the system controller supports the necessary SPI protocol for communication with the device.

Digital Potentiometers Part Context

This component belongs to the X9271 family of non-volatile digital potentiometers. Variants such as X9271TV14IZ and X9271UV14Z differ primarily in resistance values (100k vs 50k) and commercial/industrial temperature ratings. The '2.7' suffix indicates the minimum operating voltage capability.

Digital Potentiometers Replacement Considerations

Direct substitutes include X9271TV14IZ for identical electrical characteristics in tube packaging. For tape-and-reel packaging, consider X9271TV14IZ-2.7T1. Verify pin compatibility and software register mapping before replacing.
