X9271TV14I-2.7

Digital Potentiometers Overview

The X9271TV14I-2.7 is a single-channel digital potentiometer IC from the Renesas XDCP series, housed in a 14-TSSOP surface-mount package. It features a total resistance of 100 kOhms with a linear taper and 256 adjustable taps for precise control. The device utilizes a non-volatile memory architecture to retain wiper settings without power. It operates on a supply voltage range of 2.7V to 5.5V with a typical operating current of 400 uA. Communication is handled via a serial SPI interface, supporting optional address selection. The component is rated for an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Confirm RoHS compliance status for specific manufacturing lots. Check for obsolescence notices or last-time buy notifications from Renesas. Ensure ESD protection protocols are followed during handling due to CMOS technology sensitivity.

Digital Potentiometers Selection Notes

Select this model when non-volatile storage is required for wiper position. Compare against volatile variants if power-down retention is unnecessary. Verify that the 100 kOhm resistance value fits the circuit impedance requirements. Ensure the SPI bus speed and voltage levels match the host microcontroller specifications.

Digital Potentiometers Part Context

This component belongs to the X9271 family of single-channel digital potentiometers. It shares the same pinout and interface protocol with other members like the X9271UV14IZ but differs in resistance values and temperature grades. The 'T' suffix typically indicates tape and reel packaging, while 'I' denotes the industrial temperature range.

Digital Potentiometers Replacement Considerations

Direct replacements include X9271TV14IZ for tube packaging or X9271UV14IZ for commercial temperature grade applications. Cross-reference datasheets to confirm pin compatibility and electrical parameter alignment before substitution.
