X9111TV14Z-2.7

Digital Potentiometers Overview

The X9111TV14Z-2.7 is a single digitally-controlled potentiometer (XDCP) from Renesas Electronics, part of the XDCP series. It features 1024 resistor taps providing 10-bit resolution and utilizes an SPI serial interface for write, read, and transfer operations. The device operates on a system supply voltage ($V_{CC}$) ranging from 2.7V to 5.5V, with analog supplies ($V_+/V_-$) supporting dual rails from -5V to +5V. It includes four nonvolatile data registers for wiper position storage and offers a typical wiper resistance of 40Ω at 5V. The component is housed in a 14-lead TSSOP package.

Digital Potentiometers Feature Summary

• 1024-tap resolution with SPI interface for digital control
• Dual supply operation: $V_{CC}$ 2.7V–5.5V; Analog $V_+/V_-$ -5V to +5V
• Four nonvolatile data registers with power-on recall capability
• Low standby current of 5μA maximum

Digital Potentiometers Applications

• Adjusting gain in voltage amplifier circuits
• Generating programmable DC reference voltages for comparators
• Volume control in audio circuits
• Offset voltage error trimming in amplifiers
• Output voltage setting for voltage regulators

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized Renesas distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to production requirements. Ensure proper handling procedures are followed due to moisture sensitivity classification.

Digital Potentiometers Selection Notes

Select this model when a single-channel digital potentiometer with high resolution (1024 taps) and nonvolatile memory is required. Verify that the application supports the SPI interface protocol and that the dual-supply voltage range (-5V to +5V analog) aligns with system constraints. Consider the 14-TSSOP package dimensions for PCB layout compatibility.

Digital Potentiometers Part Context

This component belongs to the X9111 family of single XDCP devices. It serves as a low-power CMOS alternative to traditional mechanical potentiometers, offering electronic adjustability and data retention without external backup power. The 'Z' suffix typically indicates lead-free/RoHS compliance, while '-2.7' denotes the minimum operating voltage.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include the X9111TV14I-2.7 (industrial temperature range) or X9111TV14IZ-2.7. For applications requiring different resistance values or interfaces, consult the broader X911x series datasheets for compatible pin-outs and electrical characteristics.
