*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.
Maximum Power Dissipation
The maximum power that can be safely dissipated by the AD8024
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. Temporarily exceeding this limit 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.
Output Short Circuit Limit
The AD8024’s internal short circuit limitation is not sufficient
to protect the device in the event of a direct short circuit between
a video output and a power supply voltage rail (V
CC
or V
EE
).
Temporary short circuits can reduce an output’s ability to source
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 AD8024 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.
WARNING!

or sink current and therefore impact the device’s ability to drive
a load. Short circuits of extended duration can cause metal
lines to fuse open, rendering the device nonfunctional.
To prevent these problems, it is recommended that a series
resistor be placed as close as possible to the outputs. This will
serve to substantially reduce the magnitude of the fault currents
and protect the outputs from damage caused by intermittent
short circuits. This may not be enough 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 curve in Figure 2.
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 then 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.
