AD8072/AD8073
–4–
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 AD8072/AD8073 feature 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.

MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the AD8072
and AD8073 is limited by the associated rise in junction tem-
perature. The maximum safe junction temperature for plastic
encapsulated devices is determined by the glass transition tem-
perature of the plastic, approximately 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.
While the AD8072 and AD8073 are internally short circuit pro-
tected, this may not be sufficient to guarantee that the maximum
junction temperature (150°C) is not exceeded under all condi-
tions. To ensure proper operation, it is necessary to observe the
maximum power derating curves shown in Figures 2 and 3.
