GENERAL DESCRIPTION
The AD8509 and AD8511 are 9-channel and 11-channel LCD reference buffers, respectively, designed to drive 64 gray scale column drivers. Each buffer has an A/B input to select between two voltages for LCD displays. These buffers drive the resistor ladders of LCD column drivers for gamma correction. The LCD drivers have higher slew rates and higher output drive currents than similar competitive parts. This increases the stability of the reference ladder, resulting in better gray scale and visual performance.
