The maximum safe power dissipation in the ADA4320-1 package

the die. At approximately 150°C, which is the glass transition

temperature, the plastic changes its properties. Even temporarily

exceeding this temperature limit can change the stresses that

the package exerts on the die, permanently shifting the parametric

performance of the ADA4320-1. Exceeding a junction temperature

of 150°C for an extended time can result in changes in the silicon

devices, potentially causing 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.
