MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD816 is limited by the associated rise in junction temperature.
The maximum safe junction temperature for the plastic encap-
sulated parts is determined by the glass transition temperature
of the plastic, about 150
°
C. Exceeding this limit temporarily
may cause a shift in parametric performance due to a change in
the stresses exerted on the die by the package. Exceeding a
junction temperature of 175
°
C for an extended period can result
in device failure.
The AD816 has thermal shutdown protection, which guarantees
that the maximum junction temperature of the die remains below a
safe level. However, shorting the output to ground or either
power supply for an indeterminate period will result in device
failure. To ensure proper operation, it is important to observe
the derating curves and refer to the section on power
considerations.
It must also be noted that in high (noninverting) gain configura-
tions (with low values of gain resistor), a high level of input
overdrive can result in a large input error current, which may
result in a significant power dissipation in the input stage. This
power must be included when computing the junction tempera-
ture rise due to total internal power.

NOTES
1
Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This 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.

WARNING!
ESD SENSITIVE DEVICE
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 the AD816 features proprietary 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.
