MAXIMUM POWER DISSIPATION
Storage Temperature Range (N) –65°C to +125°C The maximum power that can be safely dissipated by the AD822 is Storage Temperature Range (R, RM) –65°C to +150°C limited by the associated rise in junction temperature. For plastic Operating Temperature Range packages, the maximum safe junction temperature is 145°C. If A Grade and B Grade –40°C to +85°C these maximums are exceeded momentarily, proper circuit Lead Temperature 260°C operation is restored as soon as the die temperature is reduced. (Soldering, 60 sec) Leaving the device in the overheated condition for an extended 1 See the Input Characteristics section. 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 While the AD822 is internally short-circuit protected, this may not stress rating only; functional operation of the product at these be sufficient to guarantee that the maximum junction temperature or any other conditions above those indicated in the operational is not exceeded under all conditions. With power supplies ±12 V or section of this specification is not implied. Operation beyond less at an ambient temperature of 25°C or less, if the output node is the maximum operating conditions for extended periods may shorted to a supply rail, then the amplifier is not destroyed, even if affect product reliability. this condition persists for an extended period.
