Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. T his is a stress rating only and 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.

MAX IMUM POWE R DISSIPAT ION
T he 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 maximum
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 “over-
heated” condition for an extended period can result in device
burnout. T o 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
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.

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 de-
tection. Although the AD811 features proprietary ESD protec-
tion circuitry, permanent damage may still occur on these
devices if they are subjected to high energy electrostatic dis-
charges. T herefore, proper ESD precautions are recommended
to avoid any performance degradation or loss of functionality.
