GENERAL DESCRIPTION

The AD8065/AD8066

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.

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 dBc @ 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

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.
