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 AD8072 and AD8073 feature 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.

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
AD8072 and AD8073 is limited by the associated rise in junc-
tion temperature. T he maximum safe junction temperature for
plastic encapsulated devices is determined by the glass transition
temperature of the plastic, approximately +150
°
C. Exceeding
this limit temporarily may cause a shift in parametric perfor-
mance 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 maxi-
mum junction temperature (+150
°
C) is not exceeded under all
conditions. T o ensure proper operation, it is necessary to ob-
serve the maximum power derating curves shown in Figures 2
and 3.
