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 an...
