BUF01901AIDRCT

Video Amps And Modules Overview

The BUF01901AIDRCT is a programmable voltage source with integrated nonvolatile memory, manufactured by Texas Instruments. It features a 10-bit digital-to-analog converter (DAC) and operates with an analog supply voltage range of 7V to 18V and a digital supply range of 2.0V to 5.5V. The device delivers an output current capability of up to 100mA while maintaining a low supply current consumption of 900µA. It utilizes an industry-standard two-wire serial interface for programming and includes high ESD protection ratings of 2kV HBM and 500V CDM.

Video Amps And Modules Feature Summary

• Supports industry-standard two-wire serial communication interface
• Features robust electrostatic discharge protection for reliable operation

Video Amps And Modules Applications

• LCD panel VCOM calibration
• LCD panel brightness and contrast control
• Programmable power supply offset adjustment
• Actuator control systems
• Motor drive applications

Video Amps And Modules Procurement Notes

Verify the specific suffix 'IDRCT' corresponds to the DFN-10 package and tape-and-reel delivery format as defined in the official ordering information. Confirm that the digital supply voltage requirements are met prior to integration, as the digital supply must be applied before the analog supply to prevent excessive current draw during startup sequences.

Video Amps And Modules Selection Notes

Select the BUF01901 variant when an external buffer or op amp is already present in the design, such as when interfacing with gamma buffers like the BUFxx70 series. This option offers a lower cost solution compared to the buffered BUF01900 version. Ensure the application requires a single-channel programmable voltage source rather than multi-channel configurations found in other family members.

Video Amps And Modules Part Context

This component belongs to the BUF0190x family of programmable voltage sources designed primarily for display driver applications. The family includes the BUF01900, which integrates a high-current buffer, and the BUF01901, which exposes the DAC output directly for use with external buffering stages. Both devices share identical control logic, memory architecture, and interface specifications.
