GENERAL DESCRIPTION  
The AD8065/AD80661 FastFET amplifiers are voltage feedback  
amplifiers with FET inputs offering high performance and ease  
of use. The AD8065 is a single amplifier, and the AD8066 is a  
dual amplifier. These amplifiers are developed in the Analog  
Devices, Inc. proprietary XFCB process and allow exceptionally  
low noise operation (7.0 nV/√Hz and 0.6 fA/√Hz) as well as  
very high input impedance.  
operate using only a 6.4 mA/amplifier typical supply current  
and are capable of delivering up to 30 mA of load current.  
The AD8065/AD8066 are high performance, high speed,  
FET input amplifiers available in small packages: SOIC-8,  
MSOP-8, and SOT-23-5. They are rated to work over the  
industrial temperature range of −40°C to +85°C.  
24  
With a wide supply voltage range from 5 V to 24 V, the ability to  
operate on single supplies, and a bandwidth of 145 MHz, the  
AD8065/AD8066 are designed to work in a variety of  
applications. For added versatility, the amplifiers also contain  
rail-to-rail outputs.

Despite the low cost, the amplifiers provide excellent overall  
performance. The differential gain and phase errors of 0.02%  
and 0.02°, respectively, along with 0.1 dB flatness out to 7 MHz,  
make these amplifiers ideal for video applications. Additionally,  
they offer a high slew rate of 180 V/µs, excellent distortion  
(SFDR of −88 dB @ 1 MHz), extremely high common-mode  
rejection of −100 dB, and a low input offset voltage of 1.5 mV  
maximum under warmed up conditions. The AD8065/AD8066
