GENERAL DESCRIPTION
The AD8065/AD8066
1
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/鈭欻z and 0.6 fA/鈭欻z) 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掳, 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/渭s, excellent distortion
(SFDR of 鈭?8 dBc @ 1 MHz), extremely high common-mode
rejection of 鈭?00 dB, and a low input offset voltage of 1.5 mV
maximum under warmed up conditions. The AD8065/ AD8066
1
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 鈭?0掳C to +85掳C.
