Hi !

 

One of the customers want to calculate the power supply current.

 

=============================================================================================

1)

For example ADUM321x has these spec.

And with this IDD(Q)has max spec.

But ADuM540x has only this

ADuM540x.JPG

 

So this means we can't calculate the MAX supply current and to calculate the supply current(TYP) ,

we have to look at each Figure.

 

Is my understanding correct?

=============================================================================================

2)

Also at the datasheet P3 ,

it says IDD1(No Viso Load) is 35mA max.

This is the supply current with the conditions,

No Load from Viso and No data communication with iCoupler .

Is my understanding correct?

=============================================================================================

 

Best regards.
