The maximum power that can be safely dissipated by the AD822 is
limited by the associated rise in junction temperature. For plastic
packages, the maximum safe junction temperature is 145°C. If
these maximums are exceeded momentarily, proper circuit
operation is restored as soon as the die temperature is reduced.
Leaving the device in the overheated condition for an extended
period can result in device burnout. To ensure proper operation, it
is important to observe the derating curves shown in Figure 27.

Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.
While the AD822 is internally short-circuit protected, this may not
be sufficient to guarantee that the maximum junction temperature
is not exceeded under all conditions. With power supplies 12 V or
less at an ambient temperature of 25°C or less, if the output node is
shorted to a supply rail, then the amplifier is not destroyed, even if
this condition persists for an extended period.
