GENERAL DESCRIPTION
The AD8027/AD80281 are high speed amplifiers with rail-to-rail input and output that operate on low supply voltages and are optimized for high performance and wide dynamic signal range. The AD8027/AD8028 have low noise (4.3 nV/√Hz, 1.6 pA/√Hz) and low distortion (120 dBc at 1 MHz). In applications that use a fraction of, or the entire input dynamic range and require low distortion, the AD8027/AD8028 are ideal choices.

FEATURES
