Overview
The AD8066AR-REEL from Analog Devices Inc. is a high-performance, dual operational amplifier (op amp) designed for a wide range of applications requiring high speed, low noise, and excellent distortion specifications. This amplifier is part of the FastFET™ series, developed using Analog Devices' proprietary XFCB process. The AD8066 offers exceptional performance with a bandwidth of up to 145 MHz, a slew rate of 180 V/µs, and very low noise operation (7.0 nV/√Hz and 0.6 fA/√Hz). It is available in an 8-lead SOIC package and operates over a wide supply voltage range from 5 V to 24 V, making it versatile for various single-supply and dual-supply configurations.
