I am using the ADA 4870 to drive the supply of a PA ( Envelope Tracking) and i want to know the current consumption of the PA only without
the current used inside the ADA 4870 , for now i am measuring the current on the supply of the ADA 4870 ( It's about 0.45A) .
the access to the current of the PA is a bit difficult write now , i am working on it.
i wanted to know is the current consumption at this current level ( 0.45 A) can be subtracted only the by the quiescent (30mA) or
it might be more than this ?
