Data Sheet AD811 ABSOLUTE MAXIMUM RATINGS MAXIMUM POWER DISSIPATION Table 2.
The maximum power that can be safely dissipated by the AD811 is

limited by the associated rise in junction temperature. For the Supply Voltage ±18 V plastic packages, the maximum safe junction temperature is 145°C. AD811JR Grade Only ±12 V For the CERDIP and LCC packages, the maximum junction tem- Internal Power Dissipation Observe Derating Curves perature is 175°C. If these maximums are exceeded momentarily, 8-Lead PDIP Package θJA = 90°C/ W proper circuit operation is restored as soon as the die tempera- 8-Lead CERDIP Package θJA = 110°C/W ture is reduced. Leaving the device in the overheated condition 8-Lead SOIC_N Package θJA = 155°C/W for an extended period can result in device burnout. To ensure 16-Lead SOIC_W Package θJA = 85°C/W proper operation, it is important to observe the derating curves 20-Lead LCC Package θJA = 70°C/W in Figure 21 and Figure 24. Output Short-Circuit Duration Observe Derating Curves Common-Mode Input Voltage ±VS While the AD811 is internally short-circuit protected, this may Differential Input Voltage ±6 V not be sufficient to guarantee that the maximum junction tem- Storage Temperature Range (Q, E) −65°C to +150°C perature is not exceeded under all conditions. An important Storage Temperature Range (N, R) −65°C to +125°C example is when the amplifier is driving a reverse-terminated Operating Temperature Range 75 Ω cable and the cable’s far end is shorted to a power supply. AD811J 0°C to +70°C With power supplies of ±12 V (or less) at an ambient temperature AD811A −40°C to +85°C of +25°C or less, and the cable shorted to a supply rail, the AD811S −55°C to +125°C amplifier is not destroyed, even if this condition persists for Lead Temperature Range 300°C an extended period.
