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 AD8278 and
AD8279 are limited by the associated rise in junction tempera-
ture (TJ) 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 performance of the amplifiers. Exceeding a
temperature of 150°C for an extended period may result in a
loss of functionality.

SHORT-CIRCUIT CURRENT
The AD8278 and AD8279 have built-in, short-circuit protection
that limits the output current (see Figure 29 for more information).
While 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
with knowledge of the supply voltages and ambient temperature of
the part, can be used to determine whether a short circuit will
cause the part to exceed its maximum junction temperature.
