PRODUCT DESCRIPTION
The AD8002 is a dual, low-power, high-speed amplifier designed
to operate on ±5 V supplies. The AD8002 features unique trans-
impedance linearization circuitry. This allows it 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°. This makes the AD8002 ideal for professional video
electronics such as cameras and video switchers. Additionally,
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 capable
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
applications where size and power are critical.

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.
