Video Amps And Modules datasheet and documents for BUF22821AIDCPR

BUF22821AIDCPR

Video Amps And Modules Overview

The BUF22821AIDCPR is a 22-channel gamma-voltage generator and Vcom calibrator manufactured by Texas Instruments. It integrates two-bank memory for configuration storage and supports standard operations up to 400kHz with high-speed data transfers up to 3.4MHz. The device is housed in a 38-pin HTSSOP (DCP) package with a 0.5mm terminal pitch, designed for TFT-LCD reference driver applications.

Video Amps And Modules Feature Summary

Integrates two-bank memory for persistent configuration storage
Supports high-speed serial data transfers up to 3.4MHz
Provides integrated Vcom calibration capabilities

Video Amps And Modules Applications

TFT-LCD reference drivers
Gamma buffer circuits
VCOM driver modules

Video Amps And Modules Procurement Notes

Verify the specific suffix DCPR to confirm the HTSSOP-38 package type and commercial temperature range. Ensure compatibility with I2C interface requirements for your system design. Confirm moisture sensitivity handling procedures are followed during assembly, as the component is classified as moisture sensitive.

Video Amps And Modules Selection Notes

Select this component when a high channel count gamma generator with integrated memory is required for LCD panels. The 22-channel output density suits complex display architectures. Verify that the 3.4MHz transfer speed meets the timing constraints of the host controller interface.

Video Amps And Modules Part Context

This part belongs to the BUF22821 family of LCD gamma buffers. It is distinct from evaluation boards like the BUF22821EVM-USB, which is used for testing the core functionality of this IC. The device serves as a critical reference voltage source for liquid crystal displays.
