This is a programmable reference voltage source BUF20800 gamma corrected generator design TFT-LCD panel.It provides 18 programmable outputs for gamma correction and two channels, each with digital Wycombe adjusted resolution.
The programmable timeconsumation replaces the traditional conversion process, optimizing various resistor gamma voltages and allowing designers to determine the correct gamma voltage to act on a panel very quickly.Necessary modifications are also easy to perform, without hardware changes.
The latest BUF20800 with titanium, small-geometry simulates the CMOS process, which makes it a very competitive option for more than just evaluating mass production.
Each output is a flexible, two-wire serial interface programmed through programming.
