超低失真高速放大器 ULTRALOW DISTORTION HIGH SPEED AMPLIFIERS
GENERAL DESCRIPTION
The AD8007 single and AD8008 dual are high performance current feedback amplifiers with ultralow distortion and noise. Unlike other high performance amplifiers, the low price and low quiescent current allow these amplifiers to be used in a wide range of applications. ’s proprietary second generation eXtra-Fast Complementary Bipolar XFCB process enables such high performance amplifiers with low power consumption.
