Overview
The AD8065ART-REEL7, produced by Analog Devices Inc., is a high-performance, single-channel operational amplifier (op amp) known as the AD8065. This device is part of the FastFET™ amplifier family, which features FET inputs, offering high performance and ease of use. The AD8065 is developed using Analog Devices' proprietary XFCB process, enabling exceptionally low noise operation and very high input impedance. It is designed to operate over a wide supply voltage range from 5 V to 24 V, making it versatile for various applications, including those requiring single supply operation.
The amplifier boasts a bandwidth of 145 MHz, rail-to-rail outputs, and a high slew rate of 180 V/μs. These characteristics, along with its low noise and high common-mode rejection, make the AD8065 ideal for high-speed and high-precision applications such as video processing and automotive systems.
