The maximum power that can be safely dissipated by the
AD811 is limited by the associated rise in junction temperature.
For the plastic packages, the maximum safe junction tempera-
ture is +145°C. For the cerdip and LCC packages, the maxi-
mum junction temperature is +175°C. If these maximums are
exceeded momentarily, proper circuit operation will be 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 in Figures 17 and 18.
While the AD811 is internally short circuit protected, this may
not be sufficient to guarantee that the maximum junction tem-
perature is not exceeded under all conditions. One important
example is when the amplifier is driving a reverse terminated
75 Ω cable and the cable’s far end is shorted to a power supply.
With power supplies of ±12 volts (or less) at an ambient tem-
perature of +25°C or less, if the cable is shorted to a supply rail,
then the amplifier will not be destroyed, even if this condition
persists for an extended period.
NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent 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.

ESD (electrostatic discharge) sensitive device. Electrostatic
charges as high as 4000 volts, which readily accumulate on the
human body and on test equipment, can discharge without
detection. Although the AD811 features proprietary ESD pro-
tection circuitry, permanent damage may still occur on these
devices if they are subjected to high energy electrostatic dis-
charges. Therefore, proper ESD precautions are recommended
to avoid any performance degradation or loss of functionality.
