board. If the thermal pad is soldered to the board, it is
also assumed it is connected to a plane. θ

MAXIMUM POWER DISSIPATION
The maximum safe power dissipation for the AD8231 is limited
by the associated rise in junction temperature (T
J
) on the die. At
approximately 130°C, which is the glass transition temperature,
the plastic changes its properties. Even temporarily exceeding
this temperature limit may change the stresses that the package
exerts on the die, permanently shifting the parametric perform-
ance of the amplifiers. Exceeding a temperature of 130°C for an
extended period can result in a loss of functionality.

For junction temperatures between 105°C and 130°C, short-circuit operation
beyond 1000 hours can impact part reliability.
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.
