MAXIMUM POWER DISSIPATION
The maximum safe power dissipation for the AD8398A is limited
by its junction temperature (T
J
) on the die. The maximum safe
T
J
of plastic encapsulated devices, as determined by the glass
transition temperature of the plastic, is 150°C. Temporarily
exceeding this limit may cause a shift in the parametric
performance due to a change in the stresses exerted on the
die by the package. Exceeding this limit for an extended period
can result in device failure.
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.
Figure 3 shows the maximum safe power dissipation in the
package vs. the ambient temperature for the 16-lead LFCSP_WQ
on a 4-layer board with six vias connecting the exposed pad to
the GND plane layer.
