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.

PRODUCT DESCRIPTION  
FREQUENCY – Hz  
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 (VS =  
±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.
