REV. 0
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 AD8114/AD8115 features proprietary ESD protection circuitry, permanent dam-
age 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
MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD8114/AD8115 is limited by the associated rise in junction
temperature. The maximum safe junction temperature for plas-
tic encapsulated devices is determined by the glass transition
temperature of the plastic, approximately +150
°
C. Temporarily
exceeding this limit may cause a shift in parametric performance
due to a change in the stresses exerted on the die by the pack-
age. Exceeding a junction temperature of +175
°
C for an ex-
tended period can result in device failure.
While the AD8114/AD8115 is internally short circuit protected,
this may not be sufficient to guarantee that the maximum junc-
tion temperature (+150
°
C) is not exceeded under all conditions.
To ensure proper operation, it is necessary to observe the maxi-
mum power derating curves shown in Figure 3.

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.
