Parameter Rating Supply Voltage ±18 V Internal Power Dissipation 8-Lead PDIP (N) Observe derating curves 8-Lead SOIC_N (R) Observe derating curves 8-Lead MSOP (RM) Observe derating curves Input Voltage1 ((V+) + 0.2 V) to ((V−) − 20 V) Output Short-Circuit Duration Indefinite Differential Input Voltage ±30 V Storage Temperature Range (N) –65°C to +125°C Storage Temperature Range (R, RM) –65°C to +150°C Operating Temperature Range A Grade and B Grade –40°C to +85°C Lead Temperature (Soldering, 60 sec) 260°C 1 See the Input Characteristics section. 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. Table 5. Thermal Resistance Package Type θJA Unit 8-lead PDIP (N) 90 °C/W 8-lead SOIC_N (R) 160 °C/W 8-lead MSOP (RM) 190 °C/W 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.
