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 AD8273 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 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 performance
of the amplifiers. Exceeding a temperature of 150°C for an
extended period can result in a loss of functionality.
The AD8273 has built-in, short-circuit protection that limits the
output current to approximately 100 mA (see Figure 2 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 negative effects on reliability.
