The outstanding 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.

The AD8002 is a dual, low power, high speed amplifier de-
signed to operate on
±
5 V supplies. The AD8002 features
unique transimpedance linearization circuitry. This allows it to
drive video loads with excellent differential gain and phase per-
formance 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°. This makes the AD8002 ideal for professional
video electronics such as cameras and video switchers. Addition-
ally, the AD8002’s low distortion and fast settling make it ideal
for buffer high speed A-to-D converters.
The AD8002 offers low power of 5.5 mA/amplifier max (V
S
=
±
5 V) and can run on a single +12 V power supply, while ca-
pable of delivering over 70 mA of load current. It is offered in
an 8-lead plastic DIP, SOIC and
µSOIC
package. These features
make this amplifier ideal for portable and battery powered appli-
cations where size and power is critical.
