GENERAL DESCRIPTION

The AD8568, AD8569, and AD8570 are low-cost, single-supply

buffer amplifiers with rail-to-rail input and output capability. They

are optimized for LCD monitor applications and built on an

advanced high voltage CBCMOS process. The AD8568 includes

two buffers, the AD8569 includes four buffers, and the AD8570

includes eight buffers.

These LCD buffers have high slew rates, 35 mA continuous

output drive, and high capacitive load drive capability. They

have a wide supply range and offset voltages below 10 mV.

The AD8568, AD8569, and AD8570 are specified over the –40

°C

to +85

°C temperature range. They are available on tape and reel,

with the AD8568 packaged in a 6-lead SOT-23, the AD8569

in a 10-lead MSOP, and the AD8570 in a 32-lead LFCSP and

20-lead TSSOP.
