MAXIMUM POWER DISSIPATION
The maximum safe power dissipation for the AD8432 is limited
by the associated rise in junction temperature (T
approximately 150°C, which is 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 amplifiers. Exceeding a temperature of 150°C for an
extended period can cause changes in silicon devices, potentially
resulting in a loss of functionality.
