DESCRIPTION  
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.  
INDUSTRY-STANDARD, TWO-WIRE

HIGH ESD RATING:  
4kV HBM, 1kV CDM, 200V MM  
This programmability replaces the traditional, time-  
consuming 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.

VCOM OUT1  
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 industry-  
standard, two-wire serial interface. Unlike existing  
programmable buffers, the BUF20800 offers a high-speed  
mode that allows clock speeds up to 3.4MHz.

The BUF20800 is available in an HTSSOP-38  
PowerPADpackage. It is specified from −40°C to +85°C.
