The maximum permissable operational
temperature can be obtained using the
equation:
T
amb ( max )
=
Power ( max ) − Power ( actual )
0.0057
+ 25°C
T
amb(max)
= Maximum operating ambient
temperature
Power (max) = Maximum power
dissipation figure, for a given V
CE
and
source resistance (R
S
)
Power (actual) = Actual power dissipation
