MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by these de-

vices is limited by the associated rise in junction temperature.

The maximum safe junction temperature for plastic encapsu-

lated devices is determined by the glass transition temperature

of the plastic, approximately +150

°C. Exceeding this limit tem-

porarily may cause a shift in parametric performance due to a

change in the stresses exerted on the die by the package. Exceed-

ing a junction temperature of +175

°C for an extended period can

result in device failure.

While the AD8047 and AD8048 are internally short circuit pro-

tected, this may not be sufficient to guarantee that the maxi-

mum junction temperature (+150

°C) is not exceeded under all

conditions. To ensure proper operation, it is necessary to ob-

serve the maximum power derating curves.

WARNING!

ESD SENSITIVE DEVICE

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 these devices feature 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.
