(1) For information on self-heating and thermal response time, see section Mounting and Thermal Conductivity.
(2) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report.
(3) The junction to ambient thermal resistance (RθJA) under natural convection is obtained in a simulation on a JEDEC-standard, High-K board as specified in JESD51-7, in an environment described in JESD51-2. Exposed pad packages assume that thermal vias are included in the PCB, per JESD 51-5.
(4) Changes in output due to self-heating can be computed by multiplying the internal dissipation by the thermal resistance.
