POWER DISSIPATION
Follow these steps to determine the Maximum power dissi-
pation for the LMH6714/LMH6720/LMH6722:
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/LMH6720/LMH6722,
package can dissipate at a given temperature can be derived
with the following equation:
