Product Introduction

This is a programmable reference voltage source BUF20800 gamma-corrected generator design TFT-LCD panel.It offers 18 programmable outputs for gamma correction and two channels, each with digital Wycombe adjusted resolution.

This programmable timesaving replaces traditional switching processes, optimizing various gamma voltage resistors and allowing designers to determine the correct gamma voltage applied to a panel very quickly.Necessary modifications are also easy to carry out without hardware changes.

Using titanium's latest BUF20800, small-geometry CMOS process, makes it a highly competitive choice, not just for mass production.

Each output is a flexible, dual-wire serial interface programmed through programming.
