X9271UV14ZT1

Digital Potentiometers Overview

The X9271UV14ZT1 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 for precise adjustment. The device incorporates non-volatile memory to retain wiper settings upon power loss and communicates via a Serial Peripheral Interface (SPI). It operates within a supply voltage range of 4.5 V to 5.5 V and supports an industrial temperature range from -40°C to +85°C. The component is housed in a 14-lead TSSOP surface-mount package.

Digital Potentiometers Feature Summary

• Single digital potentiometer configuration with 50 kOhm total resistance and 256 adjustable taps.
• Non-volatile memory retains wiper position data without external power.
• SPI serial interface for digital control and status monitoring.
• Linear taper characteristic for uniform resistance distribution.

Digital Potentiometers Applications

• Industrial process control systems requiring variable gain or offset adjustments.
• Audio equipment for digital volume control and tone shaping.
• Test and measurement instruments needing programmable reference voltages.
• Consumer electronics utilizing SPI-based configuration interfaces.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'T1' against official Renesas documentation to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status and lead-free material declarations directly with the manufacturer or authorized distributors prior to procurement.

Digital Potentiometers Selection Notes

Select this component when a 50 kOhm resistance value is required instead of the standard 100 kOhm variant. Ensure the system design accommodates the 4.5 V to 5.5 V operating voltage range. Verify that the SPI communication protocol matches the host controller's capabilities and that the TSSOP-14 footprint fits the PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the X9271 family of digital potentiometers, which are designed as drop-in replacements for mechanical potentiometers. The 'U' designation typically indicates the 50 kOhm resistance variant, while 'V' denotes the extended industrial temperature range. The 'IZ' suffix generally refers to the tube packaging, whereas 'T1' specifies the reel packaging format.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9271 variants such as X9271TV14IZ for 100 kOhm applications or X9271UV14Z for tube-packaged units. Cross-reference pinouts and electrical characteristics carefully when considering alternative manufacturers' digital potentiometers to ensure compatibility with existing SPI drivers and voltage levels.
