Stresses above those listed under Absolute Maximum Ratings
may cause permanent 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.
ESD 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 this product 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.
The AD8021 inputs are protected by diodes. Current-limiting resistors are
not used to preserve the low noise. If a differential input exceeds ±0.8 V, the
input current should be limited to ±10 mA.

MAXIMUM POWER DISSIPATION
The maximum power that can be safely dissipated by the
AD8021 is limited by the associated rise in junction tempera-
ture. The maximum safe junction temperature for plastic
encapsulated devices is determined by the glass transition
temperature of the plastic, approximately 150°C. Temporarily
exceeding this limit can 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 AD8021 is internally short-circuit protected, this can
not be sufficient to guarantee that the maximum junction tem-
perature (150°C) is not exceeded under all conditions. To ensure
proper operation, it is necessary to observe the maximum
power derating curves.
