REV. 0

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 AD8150 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.

WARNING!

ESD SENSITIVE DEVICE

MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the AD8150

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 AD8150 is internally short circuit protected, this may

not be sufﬁcient to guarantee that the maximum junction temp-

erature (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.

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.
