Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. T his 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.

MAX IMUM POWE R DISSIPAT ION
T he maximum power that can be safely dissipated by the
AD8004 is limited by the associated rise in junction tempera-
ture. T he 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 AD8004 is internally short circuit protected, this
may not be sufficient to guarantee that the maximum junction
temperature is not exceeded under all conditions. T o ensure
proper operation, it is necessary to observe the maximum power
derating curves (shown below in Figure 3).

WARNING!
ESD SENSITIVE DEVICE
C AUT ION
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 AD8004 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
