PRODUCT DESCRIPTION

The AD812 is a low power, single supply, dual video amplifier.
Each of the amplifiers have 50 mA of output current and are
optimized for driving one back-terminated video load (150 W)
each. Each amplifier is a current feedback amplifier and fea-
tures gain flatness of 0.1 dB to 40 MHz while offering differen-
tial gain and phase error of 0.02% and 0.02°. This makes the
AD812 ideal for professional video electronics such as cameras
and video switchers.

= +2, RL = 150 W
The AD812 offers low power of 4.0 mA per amplifier max (VS =
+5 V) and can run on a single +3 V power supply. The outputs
of each amplifier swing to within one volt of either supply rail to
easily accommodate video signals of 1 V p-p. Also, at gains of
+2 the AD812 can swing 3 V p-p on a single +5 V power sup-
ply. All this is offered in a small 8-lead plastic DIP or 8-lead
SOIC package. These features make this dual amplifier ideal
for portable and battery powered applications where size and
power is critical.
The outstanding bandwidth of 145 MHz along with 1600 V/ms
of slew rate make the AD812 useful in many general purpose
high speed applications where a single +5 V or dual power sup-
plies up to –15 V are available. The AD812 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
AD812 is limited by the associated rise in junction temperature.
The maximum safe junction temperature for the plastic encap-
sulated 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 AD812 is internally short circuit protected, this may
not be sufficient to guarantee that the maximum junction tem-
perature (150 degrees) 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 high (noninverting) gain configura-
tions (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 tempera-
ture rise due to total internal power.

device at these or any other conditions above those indicated in the operational

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the AD812 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.
