How can I calculate the total power dissipation of the uPC494?

Question:

How can I calculate the total power dissipation of the uPC494?

Answer:

The power consumption or dissipation of the uPC494 when operating can be calculated by monitoring the VCC pin voltage and the current that flows into the device.
Since the output stage is an open collector, the dissipation at the output stage can also be calculated by monitoring the output voltage and output current waveforms in a similar manner. The total power dissipation can therefore be determined by adding these two dissipation values together.
