THERMAL INFORMATION
The maximum power consumption an integrated circuit
can tolerate at a given operating ambient temperature can be
found from the equation:
PD(TA) =
TJ(max)–TA
RθJA (typ)
where, PD(TA) = power dissipation allowable at a given
operating ambient temperature.
4
This must be greater than the sum of the products of the
supply voltages and supply currents at the worst case
operating condition.
TJ(max) = Maximum operating junction temperature
as listed in the maximum ratings section.
TA
= Maximum desired operating ambient
temperature.
RθJA(typ) = Typical thermal resistance junction–to–
ambient.
