POWER DISSIPATION
Follow these steps to determine the Maximum power dissi-
pation for the LMH6714/6720/6722:
1. Calculate the quiescent (no load) power: P
2. Calculate the RMS power at the output stage:
3. Calculate the total RMS power: P
The maximum power that the LMH6714/6720/6722, pack-
age can dissipate at a given temperature can be derived with
the following equation:
P
(˚C) and θ
for a given package (˚C/W). For the SOIC package θ
148˚C/W, for the SOT it is 250˚C/W.
