BUF01901AIDRCR

Video Amps And Modules Overview

The BUF01901AIDRCR is a programmable voltage source with a 10-bit DAC, housed in a DFN-10 package. It operates on an analog supply of 7V to 18V and a digital supply of 2.0V to 5.5V. The device features a low supply current of 900µA and delivers up to 100mA output current. It utilizes an industry-standard two-wire interface for programming and includes onboard nonvolatile memory. The component provides rail-to-rail output and supports high ESD ratings.

Video Amps And Modules Feature Summary

• Integrates a 10-bit digital-to-analog converter with direct DAC output access
• Includes onboard one-time programmable (OTP) nonvolatile memory for data retention
• Supports standard two-wire serial communication protocols
• Features rail-to-rail output capability with high current drive

Video Amps And Modules Applications

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

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix 'DRCR' corresponds to the DFN-10 package variant as documented in the official datasheet. Confirm that the analog supply voltage meets the minimum requirement of 8.5V if OTP memory programming is required during the manufacturing process. Ensure proper handling precautions are observed due to the specified electrostatic discharge sensitivity levels.

Video Amps And Modules Selection Notes

Select this model when a cost-effective solution without an integrated buffer is required for external VCOM driver configurations. It is suitable for applications utilizing traditional gamma buffers such as the BUFxx702 or BUF11705 series. Consider the DFN-10 package dimensions for space-constrained designs like notebook computers where low profile is necessary.

Video Amps And Modules Part Context

This component belongs to the BUF0190x family of programmable voltage sources manufactured by Texas Instruments. It serves as a lower-cost alternative to the BUF01900 by omitting the internal buffer stage while retaining the core 10-bit DAC and memory functionality. The device is designed to complement existing gamma buffer architectures in display driving circuits.

Video Amps And Modules Replacement Considerations

The BUF01900 is the primary related product within the same family, distinguished by its integrated buffer stage. Other compatible devices include the BUF11705 and various BUFxx70x series gamma buffers which may utilize the BUF01901 for reference generation.
