The AD8002 is a dual, low power, high speed amplifier
designed to operate on ±5 V supplies. The AD8002 features
unique transimpedance linearization circuitry, which allows the
AD8002 to drive video loads with excellent differential gain
and phase performance on only 50 mW of power per amplifier.
The AD8002 is a current feedback amplifier and features gain
flatness of 0.1 dB to 60 MHz while offering differential gain and
phase error of 0.01% and 0.02°, which makes the AD8002 ideal
for professional video electronics such as cameras and video
switchers. Additionally, the low distortion and fast settling of
the AD8002 make it ideal for buffer high speed analog-to-
digital converters (ADCs).

The AD8002 offers a low power of 5.0 mA/amp maximum
(VS = ±5 V) and can run on a single 12 V power supply, yet is
capable of delivering over 70 mA of load current. It is offered
in 8-lead SOIC and MSOP packages. These features make this
amplifier ideal for portable and battery-powered applications
where size and power are critical.
The bandwidth of 600 MHz along with 1200 V/µs of slew rate
make the AD8002 useful in many general-purpose high speed
applications where dual power supplies of up to ±6 V and single
supplies from 6 V to 12 V are needed. The AD8002 is available
in the industrial temperature range of −40°C to +85°C.
