NOTES

permanent damage to the device. This is a stress rating only and 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

AD8079 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 tem-

perature of the plastic, approximately +150

°C. Exceeding 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 AD8079 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 derating 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 AD8079 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.
