MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD811 is limited by the associated rise in junction temper-
ature. For the plastic packages, the maximum safe junction
temperature 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 is 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 Figure 22 and Figure 25.
While the AD811 is internally short-circuit protected, this may
not be sufficient to guarantee that the maximum junction
temperature is not exceeded under all conditions. An 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 V (or less) at an ambient tempera-
ture of +25°C or less, and the cable shorted to a supply rail, the
amplifier is not destroyed, even if this condition persists for an
extended period.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent 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 CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features proprie-
tary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic
discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of
functionality.
