NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent 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.

MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
ADEL2020 is limited by the associated rise in junction tempera-
ture. For the plastic packages, the maximum safe junction
temperature is 145
°C. If the maximum is exceeded momen-
tarily, proper circuit operation will be restored as soon as the
die temperature is reduced. Leaving the device in the over-
heated condition for an extended period can result in device
burnout. To ensure proper operation, it is important to observe
the derating curves in figure 4.
While the ADEL2020 is internally short circuit protected, this
may not be sufficient to guarantee that the maximum junction
temperature is not exceeded under all conditions.

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
ADEL2020 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.
