AD8028

低失真，高速轨到轨输入/输出放大器 Low Distortion, High Speed Rail-to-Rail Input/Output Amplifiers

GENERAL DESCRIPTION

The AD8027/1 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.
