X9118TV14

Digital Potentiometers Overview

The X9118TV14 is a single-channel digitally controlled potentiometer (XDCP) from the Renesas X9118 series. It features a 100 kΩ resistive element with 1024 linear taps, providing precise digital adjustment. The device utilizes a 2-wire serial interface for control and includes non-volatile memory to retain wiper settings during power cycles. Operating voltages range from 2.7 V to 5.5 V, with a typical supply current of 3 mA. It is housed in a 14-pin TSSOP package and supports surface-mount installation.

Digital Potentiometers Feature Summary

• 100 kΩ resistance value with 1024 linear tap positions
• Non-volatile memory retains wiper position after power loss
• 2-Wire serial interface for simplified connectivity
• Single-potentiometer configuration in a 14-TSSOP package

Digital Potentiometers Applications

• Programmable gain amplifiers
• Voltage reference adjustments
• Digital volume control circuits
• Sensor biasing and calibration

Digital Potentiometers Procurement Notes

Verify the specific suffix (e.g., I for industrial, Z for commercial) as the base model X9118TV14 lacks environmental rating details. Confirm availability status, as many variants in this series are marked as obsolete or end-of-life by the manufacturer. Ensure the selected variant matches the required operating temperature range for the target application.

Digital Potentiometers Selection Notes

Select based on the required temperature grade: 'I' suffix typically denotes -40°C to +85°C, while 'Z' denotes 0°C to +70°C. Verify that the 100 kΩ total resistance aligns with circuit impedance requirements. Check if the 2-wire interface is compatible with the host controller's available pins, noting that some related models offer SPI or I2C options.

Digital Potentiometers Part Context

The X9118 belongs to the XDCP™ family of non-volatile digital potentiometers. It serves as a solid-state replacement for mechanical potentiometers in applications requiring programmable resistance. The 1024-tap resolution allows for fine-grained adjustment compared to standard 10-bit DACs driving analog switches.

Digital Potentiometers Replacement Considerations

Direct replacements include X9118TV14IZ-2.7 and X9118TV14Z-2.7, which share identical electrical specifications but differ in temperature ratings and voltage ranges. Cross-reference pinouts when substituting with other 14-pin digital potentiometers.
