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.

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.

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.
