PRODUCT DE SCRIPT ION
T he AD8002 is a dual, low power, high speed amplifier de-
signed to operate on
±
5 V supplies. T he AD8002 features
unique transimpedance linearization circuitry. T his allows it to
drive video loads with excellent differential gain and phase per-
formance on only 50 mW of power per amplifier. T he 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
°
. T his makes the AD8002 ideal for profes-
sional 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.
T he 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 being
capable of delivering over 70 mA of load current. All this is
offered in a small 8-pin DIP or 8-pin SOIC package. T hese
features make this amplifier ideal for portable and battery
powered applications where size and power is critical.
