X9119TV14I

Digital Potentiometers Overview

The X9119TV14I is a single-channel, nonvolatile digitally controlled potentiometer (XDCP) from Renesas Electronics. It features a 1024-tap linear resistor array with an end-to-end resistance of 10 kΩ and operates on a 5V supply. The device utilizes a 2-wire serial interface for control and includes four nonvolatile data registers to store wiper positions. Designed for industrial applications, it functions within a temperature range of -40°C to +85°C and is housed in a 14-lead TSSOP package.

• 1024 tap resolution with linear taper configuration
• Four nonvolatile data registers for power-on recall of wiper settings
• 2-wire serial control interface for write, read, and transfer operations

Digital Potentiometers Applications

• Programmable gain amplifiers
• Audio volume control circuits
• Voltage reference adjustment
• Offset voltage trimming in amplifier circuits

Digital Potentiometers Part Context

The X9119 belongs to the XDCP family of single-channel digital potentiometers. It shares architectural similarities with the X9118 but differs in interface type; the X9119 uses a 2-wire serial interface, whereas the X9118 typically employs SPI. Both devices offer nonvolatile memory and similar mechanical packaging options.
