APPLICATIONS INFORMATION
THERMAL PERFORMANCE
The AD9553 is specified for case temperature (TCASE). To ensure
that TCASE is not exceeded, use an airflow source. Use the following
equation to determine the junction temperature on the applica-
tion printed circuit board (PCB):
TJ = TCASE + (ΨJT × PD)
where:
TJ is the junction temperature (°C).
TCASE is the case temperature (°C) measured by the customer
at the top center of the package.
ΨJT is the value indicated in Table 23.
PD is the power dissipation (see Table 1 for the power consumption
parameters).
Values of θJA are provided for package comparison and PCB design
considerations. θJA can be used for a first-order approximation
of TJ using the following equation:
TJ = TA + (θJA × PD)
where TA is the ambient temperature (°C).
Values of θJC are provided for package comparison and PCB
design considerations when an external heat sink is required.
Values of θJB are provided for package comparison and PCB
design considerations.

1 Results are from simulations. The PCB is a JEDEC multilayer type. Thermal performance for actual applications requires careful inspection of the conditions in the
application to determine whether they are similar to those assumed in these calculations.
