NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent 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
AD8042 is limited by the associated rise in junction tempera-
ture. The maximum safe junction temperature for plastic encap-
sulated devices is determined by the glass transition temperature
of the plastic, approximately +150
°
C. Exceeding this limit tem-
porarily 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 AD8042 is internally short circuit protected, this may
not be sufficient to guarantee that the maximum junction
temperature (+150
°
C) is not exceeded under all conditions.
To ensure proper operation, it is necessary to observe the
maximum power derating curves.

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 AD8042 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.
