POWER DISSIPATION
To determine total power dissipation in a specific application,
the following equation should be applied for each output:
where:
C is load capacitance.
f is the output switching frequency.
Example: In an application where external data memory is used
and no other outputs are active, power dissipation is calculated
as follows:
