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
AMP
= I
CC
(V
CC
-V
EE
)
2. Calculate
the
RMS
power
P
(RMS) = ((V
CC
- V
(RMS))
*
I
(RMS)),
where V
and I
OUT
are the voltage and current across
the external load.
3. Calculate the total RMS power: P
T
= P
AMP
+ P
OUT
The maximum power that the LMH6714/6720/6722, pack-
age can dissipate at a given temperature can be derived with
the following equation:
P
= (150 - T
)/
θ
, where T
= Ambient temperature
(C) and
θ
= Thermal resistance, from junction to ambient,
for a given package (C/W). For the SOIC package
θ
JA
is
148C/W, for the SOT it is 250C/W.
