X9119TV14Z-2.7

Digital Potentiometers Overview

The X9119TV14Z-2.7 is a single-channel, nonvolatile digital potentiometer from the XDCP series by Renesas Electronics. It features 1024 tap positions with a 100 kΩ end-to-end resistance and linear taper. The device utilizes a 2-wire serial control interface for operation within a supply voltage range of 2.7 V to 5.5 V. Packaged in a 14-pin TSSOP, it includes four nonvolatile data registers for wiper position storage and power-on recall functionality.

Digital Potentiometers Feature Summary

• 1024-tap resolution with 100 kΩ resistance and linear taper
• Nonvolatile memory with 100-year data retention and 100,000 endurance cycles
• 2-wire serial control interface for write, read, and transfer operations
• Power-on recall loads saved wiper position from default register DR0

Digital Potentiometers Applications

• Adjusting gain in voltage amplifier circuits
• Setting programmable DC reference voltages for comparators
• Volume control in audio systems
• Offset voltage trimming in operational amplifiers

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as documentation indicates potential variations. Ensure the specific suffix matches required operating temperature ranges and packaging formats before procurement.

Digital Potentiometers Selection Notes

Select this model for applications requiring precise analog resistance adjustment via digital signals. The 2-wire interface suits systems with limited I/O pins. Verify that the 100 kΩ resistance value aligns with circuit impedance requirements and that the 2.7 V minimum supply voltage meets system power constraints.

Digital Potentiometers Part Context

This component belongs to the X9119 family of digitally controlled potentiometers. It serves as a solid-state replacement for mechanical potentiometers in space-constrained designs. The TSSOP-14 package facilitates surface-mount assembly in compact electronic devices requiring reliable parameter adjustment.

Digital Potentiometers Replacement Considerations

Cross-reference with X9111 or X9118 models for similar functionality. Note that X9111 uses an SPI interface while X9118 uses I2C; both differ from the 2-wire interface of the X9119. Verify pinout compatibility and interface protocol differences before substitution.
