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.
