1 Specification is for device in free air.

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.

MAXIMUM POWER DISSIPATION

The maximum power that can be safely dissipated by the

ADA4859-3 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.

To ensure proper operation, it is necessary to observe the

maximum power derating curves in Figure 2.
