X9119TV14

Digital Potentiometers Overview

The X9119TV14 is a single-channel digital potentiometer from the Renesas XDCP series, housed in a 14-pin TSSOP package. It features a 100 kΩ resistance value with 1024 tap positions and utilizes a 2-wire serial control interface. The device incorporates nonvolatile memory to retain wiper settings upon power loss. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an industrial temperature range of -40°C to +85°C.

Digital Potentiometers Feature Summary

• Nonvolatile memory retains wiper position after power cycle
• 1024 discrete tap positions for precise resistance adjustment
• 2-wire serial interface (SCLK, CS) for control
• Single channel configuration with linear taper

Digital Potentiometers Applications

• Audio volume control circuits
• Programmable gain amplifier biasing
• Voltage reference trimming
• Sensor calibration offset adjustment

Digital Potentiometers Procurement Notes

Verify RoHS compliance status as sources indicate conflicting data; some listings mark it non-compliant while others imply compliance. Confirm lead times and availability as the component may be subject to discontinuation notices. Ensure the specific suffix matches required voltage and temperature grades.

Digital Potentiometers Selection Notes

Select this model for applications requiring persistent resistance settings without external EEPROM. Compare against X9111 (SPI) or X9118 (I2C) if different serial interfaces are preferred. Verify that the 100 kΩ resistance and 1024 taps meet the resolution requirements of the target circuit.

Digital Potentiometers Part Context

This component belongs to the X9119 family of nonvolatile digital potentiometers. It shares architectural similarities with the X9111 and X9118 but differs primarily in its communication protocol. The TV14 designation indicates the TSSOP-14 package and specific operating conditions.

Digital Potentiometers Replacement Considerations

Direct pin-compatible substitutes include other X9119 variants with different suffixes for packaging or temperature ranges. For interface changes, consider the X9111 (SPI) or X9118 (I2C). Verify electrical parameters match before substitution.
