X9119TV14-2.7T1

Digital Potentiometers Overview

The X9119TV14-2.7T1 is a single-channel digitally controlled potentiometer (XDCP) manufactured by Renesas Electronics Corporation. It features a 100 kΩ end-to-end resistance with a linear taper and offers 1024 discrete tap positions for precise adjustment. The device utilizes a 2-wire serial control interface for communication. It operates within a supply voltage range of 2.7 V to 5.5 V and includes nonvolatile memory to retain wiper settings. The component is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP).

Digital Potentiometers Feature Summary

• 1024-tap resolution with 100 kΩ linear resistance.
• 2-wire serial control interface.
• Nonvolatile data registers for power-on recall.
• Operates on 2.7 V to 5.5 V supply.

Digital Potentiometers Applications

• Programmable gain amplifiers.
• Audio volume control circuits.
• Voltage reference trimming.

Digital Potentiometers Procurement Notes

Verify RoHS compliance status, as source data indicates non-compliance for this specific part number. Confirm the 2-wire serial interface specification against datasheets, as some family variants use SPI or I2C. Check for discontinuation notices from Renesas, as evaluation boards for this series are marked as obsolete.

Digital Potentiometers Selection Notes

Select this component when a 100 kΩ digital potentiometer with a 2-wire interface is required. Ensure the application supports the 2.7 V to 5.5 V operating range. Verify that the TSSOP-14 package dimensions fit the PCB layout constraints. Consider the ±20% tolerance if precision is critical.

Digital Potentiometers Part Context

This part belongs to the X9119 series of single digitally controlled potentiometers. It is distinct from the X9111 (SPI interface) and X9118 (I2C interface) within the same product family. The 'T1' suffix typically denotes tape and reel packaging.

Digital Potentiometers Replacement Considerations

Direct substitutes include other X9119 series variants with compatible interfaces. Cross-model replacements like the X9111 require interface adaptation due to SPI differences. Verify pin compatibility before substituting.
