PRODUCT DESCRIPTION
The AD8002 is a dual, low-power, high-speed amplifier designed 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 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 (VS = ±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.
