X9111TV14-2.7

Digital Potentiometers Overview

The X9111TV14-2.7 is a single-channel digitally controlled potentiometer (XDCP) from Renesas Electronics, housed in a 14-pin TSSOP package. It features a 100 kΩ end-to-end resistance with 1024 linear taps and an SPI serial interface for write, read, and transfer operations. The device operates on a system supply voltage of 2.7V to 5.5V and includes four nonvolatile data registers for wiper position storage. Key electrical parameters include a typical wiper resistance of 150 Ω, ±20% resistance tolerance, and a temperature coefficient of ±300ppm/°C. It supports power-on recall of the default wiper position and maintains data retention for up to 100 years.

Digital Potentiometers Procurement Notes

Verify component status as the X9111 series is listed as discontinued by multiple distributors. Confirm availability through authorized channels or secondary markets. Ensure compatibility with existing PCB footprints and SPI communication protocols before procurement.

Digital Potentiometers Selection Notes

Select this component for applications requiring precise digital adjustment of analog signals without mechanical components. Verify that the 100 kΩ resistance range and 1024 tap resolution meet circuit requirements. Ensure the SPI interface matches the host controller's capabilities and that the 2.7V–5.5V supply range aligns with the system design.

Digital Potentiometers Part Context

The X9111 belongs to the XDCP™ family of digitally controlled potentiometers. It integrates a single potentiometer with nonvolatile memory on a monolithic CMOS IC. The device replaces mechanical trimmers in applications requiring programmable resistance adjustments, offering improved reliability and reduced size.

Digital Potentiometers Replacement Considerations

Check for direct pin-compatible replacements within the X9111 series or other Renesas XDCP devices. Verify interface compatibility (SPI vs. I2C) and resistance values when considering alternative manufacturers.
