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