Overview
The AD8008ARZ-REEL7, produced by Analog Devices Inc., is a high-performance dual current feedback operational amplifier. It is part of the AD8007/AD8008 series, known for their ultralow distortion and noise characteristics. These amplifiers are fabricated using Analog Devices' proprietary second-generation eXtra-Fast Complementary Bipolar (XFCB) process, which enables high performance with low power consumption. The AD8008 is particularly suited for a wide range of applications due to its low quiescent current, wide supply voltage range (5 V to 12 V), and high bandwidth.
