PRODUCT DESCRIPTION
The AD8013 is a low power, single supply, triple video
amplifier. Each of the three amplifiers has 30 mA of output
current, and is optimized for driving one back terminated video
load (150
) each. Each amplifier is a current feedback amp-
lifier and features gain flatness of 0.1 dB to 60 MHz while offering

differential gain and phase error of 0.02% and 0.06
. This
makes the AD8013 ideal for broadcast and professional video
electronics.
The AD8013 offers low power of 4 mA per amplifier max and
runs on a single +5 V to +13 V power supply. The outputs of
each amplifier swing to within one volt of either supply rail to
easily accommodate video signals. The AD8013 is unique
among current feedback op amps by virtue of its large capacitive
load drive. Each op amp is capable of driving large capacitive
loads while still achieving rapid settling time. For instance it
can settle in 18 ns driving a resistive load, and achieves 40 ns
(0.1%) settling while driving 200 pF.
The outstanding bandwidth of 140 MHz along with 1000 V/
s
of slew rate make the AD8013 useful in many general purpose
high speed applications where a single +5 V or dual power
supplies up to
6.5 V are required. Furthermore the AD8013's
high speed disable function can be used to power down the
amplifier or to put the output in a high impedance state. This
can then be used in video multiplexing applications. The
AD8013 is available in the industrial temperature range of
40
C to +85
C.

Maximum Power Dissipation
The maximum power that can be safely dissipated by the AD8013
is limited by the associated rise in junction temperature. The
maximum safe junction temperature for the plastic encapsulated
parts is determined by the glass transition temperature of the
plastic, about 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 AD8013 is internally short circuit protected, this may
not be enough to guarantee that the maximum junction temper-
ature is not exceeded under all conditions. To ensure proper
operation, it is important to observe the derating curves.
It must also be noted that in (noninverting) gain configurations
(with low values of gain resistor), a high level of input overdrive
can result in a large input error current, which may result in a
significant power dissipation in the input stage. This power
must be included when computing the junction temperature rise
due to total internal power.

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. Although
the AD8013 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recom-
mended to avoid performance degradation or loss of functionality.
