POWER DISSIPATION EXAMPLE
To determine total power dissipation in a specific application,
the following equation should be applied for each output:
C = load capacitance, f = output switching frequency.
Example:
In an ADSP-2103 application where external data memory is
used and no other outputs are active, power dissipation is
calculated as follows:
