X9111TV14IZ-2.7

Digital Potentiometers Overview

The X9111TV14IZ-2.7 is a single-channel digitally controlled potentiometer (XDCP) from the XDCP series, manufactured by Renesas Electronics Corporation. It features an end-to-end resistance of 100 kOhms with 1024 taps for 10-bit resolution. The device utilizes a nonvolatile memory architecture to store wiper positions and operates on a supply voltage range of 2.7V to 5.5V. Communication is handled via an SPI serial interface. The component is housed in a 14-pin TSSOP package and supports an operating temperature range from -40°C to +85°C.

Digital Potentiometers Procurement Notes

This component is identified as End-of-Life (EOL) by the manufacturer. Availability is restricted or limited across distributors. Verification of specific stock status and alternative sourcing strategies is required before procurement planning due to discontinuation status.

Digital Potentiometers Selection Notes

Select this part for applications requiring high-resolution digital adjustment of 100 kOhm resistive networks. Ensure the system interface supports SPI protocols. Verify that the analog voltage rails do not exceed the ±5V limit relative to VCC. Consider the EOL status when designing for long-term production runs.

Digital Potentiometers Part Context

The X9111 belongs to the X911x family of single-digitally controlled potentiometers. This series integrates CMOS technology with nonvolatile storage to maintain settings without power. The TV14IZ suffix indicates the specific pinout, package type (TSSOP-14), and industrial temperature grade variants within the broader product line.

Digital Potentiometers Replacement Considerations

As the X9111TV14IZ-2.7 is discontinued, verify functional equivalents such as the X9110 or X9118 series if interface compatibility differs. Cross-reference datasheets for pinout and electrical parameter alignment to ensure direct replacement feasibility.
