I need to design a headphone amplifier with TPA6120 chip, because I don't have much knowledge about amplifier design & construction.
I'm trying to do the design as compact as possible with full SMD components. So I'm thinking of to make power supply as a seperate(wall mount adapter) or integrated(with transformers & LDO's, which will be big in size).
Now I have a doubt in my mind about the power consumption of the chip. As you can see in the attachment, the power consumption of the chip internal circuitary is very less. But the output current is 700mA which is very high. The output is not a DC voltage, so i assume that the mentioned current is a peak current. Please clarify this.
How much (RMS)current I can consider to design a power supply for the TPA6120 headphone amplifier chip?
