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 AD8380 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.

MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD8380 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 junc-
tion temperature of 175°C for an extended period can result in
device failure.
Output Short Circuit Limit
The AD8380’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
porary short circuits can reduce an output’s ability to source 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 of 25 Ω or greater be placed as close as possible to the
AD8380’s video 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 derat-
ing curve in Figure 2 below.
