Stresses above those listed under Absolute Maximum Ratings
may cause permanent 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 AD8005
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
causes 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 AD8005 is internally short circuit protected, this is
not sufficient to guarantee that the maximum junction temper-
ature (+150°C) is not exceeded under all conditions. To ensure
proper operation, it is necessary to observe the maximum
power derating curves shown in Figure 5.
