AD8479-EP Enhanced Product ABSOLUTE MAXIMUM RATINGS Table 2. THERMAL RESISTANCE Parameter Rating
Thermal performance is directly linked to printed circuit board VS ±18 V (PCB) design and operating environment. Careful attention to Input Voltage Range PCB thermal design is required. Continuous ±600 V θJA is the natural convection, junction to ambient thermal Common-Mode and Differential, ±900 V resistance measured in a one cubic foot sealed enclosure. 10 sec Output Short-Circuit Duration Indefinite θJC is the junction to case thermal resistance. REF(−) and REF(+) −VS − 0.3 V to +VS + 0.3 V
