For junction temperatures between 105°C and 130°C, short-circuit operation

beyond 1000 hours can impact part reliability.

Stresses at or above those listed under Absolute Maximum

Ratings may cause permanent damage to the product. This is a

stress rating only; functional operation of the product at these

or any other conditions above those indicated in the operational

section of this specification is not implied. Operation beyond

the maximum operating conditions for extended periods may

affect product reliability.

The θJA values in Table 5 assume a 4-layer JEDEC standard

board. If the thermal pad is soldered to the board, it is

also assumed it is connected to a plane. θJC at the exposed pad

is 6.3°C/W.

MAXIMUM POWER DISSIPATION

The maximum safe power dissipation for the AD8231 is limited

by the associated rise in junction temperature (TJ) 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.
