X9119TV14IZ-2.7T1

Digital Potentiometers Overview

The X9119TV14IZ-2.7T1 is a single-channel nonvolatile digital potentiometer from the XDCP series, manufactured by Renesas Electronics Corporation. It features a 100 kΩ end-to-end resistance with a linear taper and 1024 tap positions for precise control. The device utilizes a 2-wire serial interface for write, read, and transfer operations. It operates on a system supply voltage (VCC) ranging from 2.7 V to 5.5 V and supports analog supplies (V+/V-) from -5 V to +5 V. Key electrical parameters include a typical wiper resistance of 40 Ω at 5 V and a maximum standby current of 5 μA. The component is housed in a 14-lead TSSOP package.

Digital Potentiometers Feature Summary

• Nonvolatile memory stores four data registers, enabling power-on recall of saved wiper positions.
• 10-bit resolution provided by 1024 resistor taps within the 100 kΩ array.
• Low power consumption with a maximum standby current of 5 μA.
• Robust data retention specified at 100 years with an endurance of 100,000 data changes per bit.

Digital Potentiometers Applications

• Adjusting gain levels in voltage amplifier circuits.
• Setting programmable DC reference voltages for comparators and detectors.
• Volume control in audio signal processing applications.
• Trimming offset voltage errors in operational amplifier circuits.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'IZ' against official datasheets to confirm industrial temperature range (-40°C to +85°C) and RoHS compliance status. Cross-reference the 'T1' tape-and-reel designation with manufacturer packaging specifications to ensure correct handling requirements. Confirm availability status as distribution listings indicate potential discontinuation or limited stock conditions.

Digital Potentiometers Selection Notes

Select this component when a single-channel digital potentiometer with high resolution (1024 taps) and nonvolatile storage is required. Ensure the application voltage does not exceed the 5.5 V VCC limit or the ±5 V analog supply range. Verify that the 2-wire serial interface is compatible with the host controller's communication protocol. Consider the 14-TSSOP package dimensions for PCB layout constraints.

Digital Potentiometers Part Context

This part belongs to the X9119 family of digitally controlled potentiometers, which are CMOS-based integrated circuits designed to replace mechanical trimmers. The X9119 variant specifically offers a 100 kΩ resistance value, distinguishing it from other family members like the X9111 (100 kΩ SPI) or X9116 (lower tap count). The device integrates a volatile Wiper Counter Register (WCR) and four nonvolatile Data Registers for flexible configuration.

Digital Potentiometers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate pin-compatible alternatives within the X9119 series or general-purpose digital potentiometers with matching 100 kΩ resistance, 1024 taps, and 2-wire serial interfaces.
