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.

MAXIMUM POWER DISSIPATION
The maximum safe power dissipation for the AD8271 is limited
by the associated rise in junction temperature (T
J
) on the die. At
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 perfor-
mance of the amplifiers. Exceeding a temperature of 150°C for
an extended period of time can cause changes in silicon devices,
potentially resulting in a loss of functionality.
The AD8271 has built-in short-circuit protection that limits
the output current to approximately 100 mA (see Figure 22 for
more information). Although the short-circuit condition itself
does not damage the part, the heat generated by the condition
can cause the part to exceed its maximum junction temperature,
with corresponding negative effects on reliability.
