X9118TV14I-2.7

Digital Potentiometers Overview

The X9118TV14I-2.7 is a single digitally controlled potentiometer (XDCP) from the Renesas X9118 series, housed in a 14-pin TSSOP package. It features a 100 kΩ end-to-end resistance with a linear taper and 1024 taps for precise adjustment. The device utilizes a 2-Wire serial interface for control and includes non-volatile memory to retain wiper positions. It operates on a supply voltage ranging from 2.7 V to 5.5 V, with a maximum operating current of 3 mA across an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• 1024-tap resolution with 100 kΩ linear resistance
• Non-volatile data registers for power-on recall
• 2-Wire serial interface for write/read operations
• Low power consumption with 3 mA typical operating current

Digital Potentiometers Applications

• Adjusting gain in voltage amplifier circuits
• Setting programmable DC reference voltages
• Audio volume control applications
• Offset voltage trimming in operational amplifiers

Digital Potentiometers Procurement Notes

This component is identified as End-of-Life (EOL) by the manufacturer. Availability is restricted, and sourcing may require checking secondary distributors or verifying specific stock conditions. Designers should review discontinuance notifications and consider long-term supply constraints before finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this model when a single-channel digital potentiometer with 100 kΩ resistance and 2-Wire interface compatibility is required. Ensure the application supports the 2.7 V to 5.5 V supply range and requires non-volatile storage for wiper settings. Verify that the TSSOP-14 package fits the PCB layout constraints.

Digital Potentiometers Part Context

The X9118 belongs to the XDCP™ family of single digitally controlled potentiometers. It serves as a solid-state alternative to mechanical potentiometers, offering higher reliability and smaller form factors. The 'I' suffix indicates the industrial temperature grade, while '2.7' denotes the minimum operating voltage capability.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers should evaluate parametrically similar devices from the same manufacturer or other vendors, ensuring compatibility with the 2-Wire interface and 100 kΩ resistance value.
