POWER DISSIPATION

Follow these steps to determine the Maximum power dissipation for the LMH6714/LMH6720/LMH6722:

1. Calculate the quiescent (no load) power: PAMP = ICC (VCC -VEE)

2. Calculate the RMS power at the output stage: POUT (RMS) = ((VCC - VOUT (RMS)) * IOUT (RMS)), where VOUT

and IOUT are the voltage and current across the external load.

3. Calculate the total RMS power: PT = PAMP + POUT

The maximum power that the LMH6714/LMH6720/LMH6722, package can dissipate at a given temperature can

be derived with the following equation:

PMAX = (150° - TA)/ θJA, where TA = Ambient temperature (°C) and θJA = Thermal resistance, from junction to

ambient, for a given package (°C/W). For the SOIC package

θJA is 145°C/W, for the 5-pin SOT-23 it is 232°C/W.
