AD790 ABSOLUTE MAXIMUM RATINGS1, 2
Supply Voltage . ± 18 V Internal Power Dissipation2 . 500 mW Differential Input Voltage . ± 16.5 V Output Short-Circuit Duration . Indefinite Storage Temperature Range (N, R) . –65°C to +125°C (Q) . –65°C to +150°C Lead Temperature Range (Soldering 60 sec) . 300°C Logic Supply Voltage . 7 V NOTES 1Stresses above those listed under “Absolute Maximum Ratings” may cause perma- nent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 2Thermal characteristics: plastic N-8 package: θJA = 90°C/watt; ceramic Q-8 package: θJA = 110°C/watt, θJC = 30°C/watt. SOIC (R-8) package: θJA = 160°C watt; θJC = 42°C/watt.
