MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the

AD8055/AD8056 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.

Exceeding this limit temporarily can 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.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent 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.

While the AD8055/AD8056 are 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.

ESD 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 this product 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.
