GENERAL 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, which allows the

AD8002 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°, which makes the AD8002 ideal

for professional video electronics such as cameras and video

switchers. Additionally, the low distortion and fast settling of

the AD8002 make it ideal for buffer high speed analog-to-

digital converters (ADCs).

Figure 1.

The AD8002 offers a low power of 5.0 mA/amp maximum

(VS = ±5 V) and can run on a single 12 V power supply, yet is

capable of delivering over 70 mA of load current. It is offered

in 8-lead SOIC and MSOP packages. These features make this

amplifier ideal for portable and battery-powered applications

where size and power are critical.

The 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.
