How Do You Calculate Power Efficiency in DTC Networks?

[cbausch]

Hi,
I am trying to model a phones increased performance due to the integration of a DTC network. I have the spec sheet on the part but for the live of me cannot interpret it to generate the information I need. I need to find the Power in and out of the component to determine gain and efficiency. They give me supply Voltage and Current so I can find supply Power...(right?), but the rest is in terms I can't understand. Which of the specs should I focus on, and what might they be termed?
Also for Power IN is that the same as Supply Power or do I need a power factor? Any help would be sooo appreciated.
Thank you,
Christa

Yes, the power in and supply power are the same thing. The supply is DC correct? If so, then you don't need a power factor.

In a signal processing chip, supply power is typically much larger than signal power.
