LCD Gamma Buffers 18-Ch Vltg Generator w/2 Prog VCOM Chs
The BUF20800 is a programmable voltage reference generator designed for gamma correction in TFT-LCD panels. It provides 18 programmable outputs for gamma correction and two channels for VCOM adjustment, each with 10-bit resolution.
This programmability replaces the traditional, timeconsuming process of changing resistor values to optimize the various gamma voltages and allows designers to determine the correct gamma voltages for a panel very quickly. Required changes can also be easily implemented without hardware changes.
The BUF20800 uses TI's latest, small-geometry analog CMOS process, which makes it a very competitive choice for full production, not just evaluation.
Programming of each output occurs through an industrystandard,two-wire serial interface. Unlike existing programmable buffers, the BUF20800 offers a high-speed mode that allows clock speeds up to 3.4MHz.For lower channel count, please contact your local sales or marketing representative.
The BUF20800 is available in an HTSSOP-38 PowerPAD package. It is specified from −40°C to +85°C.
