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.
THERMAL RESISTANCE
θJA is specified for the worst-case conditions, that is, a device
soldered in a circuit board for surface-mount packages.

MAXIMUM POWER DISSIPATION
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.
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.
