MAXIMUM POWER DISSIPATION

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.

ESD SUSCEPTIBILITY

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.
