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

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 (V
±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.

NOTES

1

Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

Specification is for device in free air:

8-Lead Plastic DIP Package: θJA = 90°C/W
8-Lead SOIC Package: θJA = 155°C/W
8-Lead µSOIC Package: θJA = 200°C/W

MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the
AD8002 is limited by the associated rise in junction tempera­ture. The maximum safe junction temperature for plastic
encapsulated devices is determined by the glass transition tem­perature of the plastic, approximately 150°C. Exceeding this
limit temporarily may cause a shift in parametric performance
due to a change in the stresses exerted on the die by the package.
Exceeding a junction temperature of 175°C for an extended
period can result in device failure.

While the AD8002 is internally short circuit protected, this
may not be sufficient to guarantee that the maximum junction
temperature (150°C) is not exceeded under all conditions. To
ensure proper operation, it is necessary to observe the maximum
power derating curves.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.

WARNING!

Although the AD8002 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
