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 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.
