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
AD8031/AD8032 are limited by the associated rise in junction
temperature. The maximum safe junction temperature for
plastic encapsulated devices is determined by the glass transi-
tion temperature of the plastic, approximately +150
°
C. Ex-
ceeding 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 AD8031/AD8032 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. To ensure proper operation, it is necessary to
observe the maximum power derating curves shown in Figure 2.

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 AD8031/AD8032 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.
WARNING!
ESD SENSITIVE DEVICE
(continued from page 1)
Operating on supplies from +2.7 V to +12 V and dual supplies up
to
±
6 V, the AD8031/AD8032 are ideal for a wide range of applica-
tions, from battery operated systems with large bandwidth re-
quirements to high speed systems where component density re-
quires lower power dissipation. The AD8031/AD8032 are available
in 8-lead plastic DIP and SOIC packages and will operate over the
industrial temperature range of –40
°
C to +85
°
C. The AD8031A is
also available in the space-saving 5-lead SOT-23-5 package and the
AD8032A is available in the 8-lead
μ
SOIC package.
