MAXIMUM POWER DISSIPATION

The maximum safe power dissipation for the ADA4805-1/

ADA4805-2 is limited by the associated rise in junction

the glass transition temperature, the properties of the plastic

change. Even temporarily exceeding this temperature limit may

change the stresses that the package exerts on the die, permanently

shifting the parametric performance of the ADA4805-1/ADA4805-2.

Exceeding a junction temperature of 175C for an extended

period of time can result in changes in silicon devices, potentially

causing degradation or loss of functionality.
