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.
