X9111TV14I-2.7

Digital Potentiometers Overview

The X9111TV14I-2.7 is a single-channel digital potentiometer from the XDCP series, manufactured by Renesas Electronics Corporation. It features a 100 kΩ end-to-end resistance with linear taper and 1024 taps for precise control. The device operates on a supply voltage of 2.7 V to 5.5 V and utilizes an SPI serial interface for write, read, and transfer operations. It includes four nonvolatile data registers for wiper position storage and power-on recall functionality. The component is housed in a 14-TSSOP package and supports an operating temperature range of -40°C to 85°C.

Digital Potentiometers Feature Summary

• 1024-tap resolution with 100 kΩ resistance and ±20% tolerance
• SPI serial interface for digital control
• Four nonvolatile data registers with power-on recall
• Low standby current (5 μA maximum)

Digital Potentiometers Applications

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

Digital Potentiometers Procurement Notes

This component is officially listed as End of Life (EOL) by the manufacturer. Verification of availability should focus on distributor stock status or alternative sourcing channels, as standard production orders are no longer accepted. Confirm RoHS compliance and specific packaging details through official datasheets before procurement planning.

Digital Potentiometers Selection Notes

Select this part for applications requiring high-resolution analog adjustment via digital signals. Ensure the system voltage falls within the 2.7 V to 5.5 V range. Verify that the SPI interface timing matches the controller capabilities. Consider the 100 kΩ resistance value against load requirements and the 150 Ω typical wiper resistance impact on signal integrity.

Digital Potentiometers Part Context

The X9111 belongs to the XDCP family of digitally controlled potentiometers. It serves as a CMOS-based replacement for mechanical potentiometers in space-constrained designs. The TV14 suffix indicates the 14-TSSOP package variant, while the I-2.7 designation specifies the industrial temperature grade and minimum supply voltage capability.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers should evaluate newer generations of digital potentiometers from Renesas or other manufacturers with compatible pinouts and electrical specifications.
