MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the AD8183/

AD8185 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 AD8183/AD8185 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 shown in Figure 2.

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 AD8183/AD8185 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.
