X9111TV14Z

Digital Potentiometers Overview

The X9111TV14Z is a single-channel non-volatile digital potentiometer from the Renesas XDCP series. It features a resistance value of 100 kΩ with 1024 taps and linear taper characteristics. The device utilizes an SPI interface for control and operates within a supply voltage range of 2.7V to 5.5V. Packaged in a 14-TSSOP surface-mount enclosure, it supports an operating temperature range of -40°C to 85°C. Key electrical specifications include a contact resistance of 150 Ω (typical), a tolerance of ±20%, and a temperature coefficient of ±300ppm/°C.

Digital Potentiometers Procurement Notes

This component is officially listed as End-of-Life (EOL) by Renesas Electronics Corporation. Public records indicate discontinuation notifications effective June 25, 2021. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory, as standard production has ceased.

Digital Potentiometers Selection Notes

Select this part for applications requiring precise, non-volatile resistance adjustment via SPI. Ensure the system voltage falls between 2.7V and 5.5V. Verify that the 100kΩ resistance and 1024-tap resolution meet circuit requirements. Consider the 14-TSSOP package dimensions for PCB layout compatibility.

Digital Potentiometers Part Context

The X9111 belongs to the XDCP™ family of digitally controlled potentiometers. It is functionally similar to other models in the series but distinguished by its specific resistance value, interface type, and packaging. It serves as a solid-state replacement for mechanical potentiometers in space-constrained designs.

Digital Potentiometers Replacement Considerations

Public data lists the X9111TV14I-2.7 as a variant within the same product line. Engineers should verify pinout compatibility and electrical parameters before substituting. No other direct cross-model substitutes are confirmed in the provided documentation.
