ADDITIONAL DOCUMENTATION
THERMAL ADDENDUM (REV 2.0)
Device on Thermal Test Board
RθJA is the thermal resistance between die junction and
ambient air.
This device is a dual die package. Index m indicates the
die that is heated. Index n refers to the number of the die
where the junction temperature is sensed.
