Input current for HFDA80D

[PS5]

Hi,

I am using HFDA80D Amplifier in my design.

I need details regarding required input current for 12V input and 4 ohms 100W output.

How much "details" do you need for an amplifier?

A Class-D amplifier has around 85 - 90% efficiency, so for 100W output you need to supply something like 115W.
