低成本， 300 MHz轨到轨放大器 Low Cost, 300 MHz Rail-to-Rail Amplifiers
GENERAL DESCRIPTION
The AD8061/AD8062/AD8063 are rail-to-rail output voltage feedback amplifiers offering ease of use and low cost. They have a bandwidth and slew rate typically found in current feedback amplifiers. All have a wide input common-mode voltage range and output voltage swing, making them easy to use on single supplies as low as 2.7 V.
