NOTES

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

AD8391 is limited by the associated rise in junction temperature.

The maximum safe junction temperature for a plastic encapsu-

lated device 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.

To ensure proper operation, it is necessary to observe the maxi-

mum power derating curve.

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 AD8391 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.
