PRODUCT DESCRIPTIONThe AD8001 is a low power, high-speed amplifier designed
to operate on–5V supplies. The AD8001 features unique

transimpedance linearization circuitry. This allows it to drive
video loads with excellent differential gain and phase perfor-
mance ononly 50mW of power. The AD8001 is a current
feedback amplifier and features gain flatness of 0.1 dB to 100 MHz
while offering differential gain and phase error of 0.01% and
0.025°. This makes the AD8001 ideal for professional video
electronics such as cameras and video switchers. Additionally,
the AD8001’s low distortion and fast settling make it ideal for
buffer high-speed A-to-D converters.
The AD8001 offers low power of 5.5 mA max (VS = –5 V) and
can run on a single +12 V power supply, while being capable of
delivering over 70 mA of load current. These features make this
amplifier ideal for portable and battery-powered applications
where size and power are critical.
The outstanding bandwidth of 800 MHz along with 1200 V/ms
of slew rate make the AD8001 useful in many general purpose
high-speed applications where dual power supplies of up to –6 V
andsinglesuppliesfrom6Vto12Vareneeded.TheAD8001is
availableintheindustrialtemperaturerangeof–40°C to +85°C.

NOTESStresses 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: qJA = 90°C/W
8-Lead SOIC Package: qJA = 155°C/W
8-Lead Cerdip Package: qJA = 110°C/W
5-Lead SOT-23-5 Package: qJA = 260°C/W
MAXIMUM POWER DISSIPATIONThe maximum power that can be safely dissipated by the
AD8001 is limited by the associated rise in junction tempera-
ture. The maximum safe junction temperature for plastic
encapsulated devices is determined by the glass transition tem-
perature 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 AD8001 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.

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