X9111TV14

Digital Potentiometers Overview

The X9111TV14 is a single-channel nonvolatile digital potentiometer from Renesas Electronics, part of the XDCP series. It features a 100kΩ end-to-end resistance with linear taper and 1024 tap positions for precise control. The device operates on a supply voltage range of 2.7V to 5.5V and utilizes an SPI serial interface for write, read, and transfer operations. It includes four nonvolatile data registers that retain wiper positions during power loss, with power-on recall functionality loading the default register upon startup. The component is housed in a 14-TSSOP surface-mount package.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains up to four wiper positions with 100-year data retention and 100,000 endurance cycles per bit.
• SPI serial interface supports independent write, read, and transfer operations for efficient system integration.
• Power-on recall automatically loads the saved wiper position from the default data register (DR0) upon initialization.
• Operates within a wide supply voltage range of 2.7V to 5.5V with low standby current of 5μA maximum.

Digital Potentiometers Applications

• Adjusting gain levels in voltage amplifier circuits.
• Providing programmable DC reference voltages for comparators and detectors.
• Volume control in audio signal processing applications.
• Trimming offset voltage errors in amplifier circuits.
• Calibrating Wheatstone bridge resistance values.

Digital Potentiometers Procurement Notes

Verify component status as the X9111 series may be discontinued or subject to product change notices. Confirm specific suffix requirements for voltage ranges and packaging formats against current manufacturer documentation before procurement planning.

Digital Potentiometers Selection Notes

Select this model for applications requiring precise digital adjustment of analog parameters without mechanical components. Ensure the 100kΩ resistance value matches circuit requirements. Verify SPI compatibility with the host microcontroller and confirm that the 14-TSSOP package fits the PCB layout constraints.

Digital Potentiometers Part Context

The X9111 belongs to the XDCP™ family of digitally controlled potentiometers. It serves as a solid-state alternative to mechanical pots, offering higher reliability and smaller form factors. The device integrates a volatile Wiper Counter Register (WCR) and nonvolatile Data Registers (DRs) to manage resistor array switching via the SPI bus.

Digital Potentiometers Replacement Considerations

The X9110 is identified as a dual-supply version of the X9111. Check datasheets for pinout and voltage range compatibility when considering substitutes. Verify if alternative models support the same 1024-tap resolution and nonvolatile storage capabilities.
