NOTES

1Stresses 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.

2Specification is for the device in free air:

8-Lead SOIC Package: θJA = 160°C/W.

8-Lead microSOIC Package: θJA = 200°C/W.

MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the AD8022

is limited by the associated rise in junction temperature. 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

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 AD8022 is internally short circuit protected, this may not

be sufficient to guarantee that the maximum junction temperature

(150°C) is not exceeded under all conditions. To ensure proper

operation, it is necessary to observe the maximum power derat-

ing curves.

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 AD8022 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.
