GENERAL DESCRIPTION

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 volt-

ages for LCD displays. These buffers are used to drive the resis-

tor ladders of LCD column drivers for gamma correction.

These LCD drivers have higher slew rates and output drive cur-

rent than similar competitive parts. This increases the stability

of the reference ladder, resulting in better gray scale and visual

performance.

The AD8509 and AD8511 are specified over the –20°C to +85°C

temperature range. They are available in 48-lead thin shrink small

outline (TSSOP) surface mount packages in tape and reel.
