GENERAL DESCRIPTION
The ADD8506 has 6-channel LCD gamma reference buffers designed to drive column driver gamma inputs in line inversion panels. Each buffer channel has an A/B input to select between two gamma voltage curves. These buffer channels drive the resistor ladders of LCD column drivers for gamma correction. The ADD8506 outputs have high slew rates and output drives that increase the stability of the reference ladder,...
