X9279TV14-2.7

Digital Potentiometers Overview

The X9279TV14-2.7 is a single-channel digitally controlled potentiometer (XDCP) manufactured by Intersil, now part of Renesas Electronics. This component features a 100 kΩ resistance value with 256 discrete taps for precise digital adjustment. It utilizes a 2-wire serial control interface and includes non-volatile memory to retain wiper positions during power loss. The device operates on supply voltages ranging from 2.7 V to 5.5 V and is housed in a TSSOP-14 package.

Digital Potentiometers Feature Summary

• Single channel configuration with 100 kΩ total resistance
• 256 tap resolution for fine adjustment
• Non-volatile memory stores up to four wiper positions
• 2-wire serial interface compatible with standard protocols

Digital Potentiometers Applications

• Battery-powered systems requiring low standby current
• Audio volume control applications
• Programmable gain amplifier circuits
• Voltage reference trimming

Digital Potentiometers Procurement Notes

Verify the manufacturer status as Intersil was acquired by Renesas Electronics. Confirm RoHS compliance and lead times through authorized distributors. Check for end-of-life notices or recommended new design alternatives if available.

Digital Potentiometers Selection Notes

Select this component when a single potentiometer with high resolution (256 taps) and non-volatile storage is required. Ensure the system voltage falls within the 2.7 V to 5.5 V range. Verify that the 2-wire serial interface matches the microcontroller's communication capabilities.

Digital Potentiometers Part Context

This part belongs to the X9279 series of single XDCPs. It shares architectural similarities with other Intersil digital potentiometers but is distinguished by its specific 100 kΩ resistance and 256-tap resolution. The 'T' suffix typically indicates tape and reel packaging, while 'V14' denotes the TSSOP-14 package type.

Digital Potentiometers Replacement Considerations

Check for direct substitutes such as the ISL22316 or ISL22319 series from Renesas/Intersil. Verify pin compatibility and electrical specifications before substitution.
