Hi !
I saw the datasheet about ADuM140.
http://www.analog.com/media/en/technical-documentation/data-sheets/ADuM140D_140E_141D_141E_142D_142E.pdf
For example , ADuM140D/E's supply current is this.
1)
I think this data is 50%-duty.
Is it correct?
2)
And about OOK, I think if I input Low only , oscillator will stop.
So, I will be able to decrease supply current.
Is my understanding is correct?
3)
And if No.2 question is correct, will ADuM14* 's supply current will proportional to DUTY?
And if you have a data about this, can you show me to us?
4)
And do you have a schedule to release smaller package.
For example ,SSOP or more smaller.
Best regards.

You are right - there is a typo in the ADuM14x datasheet. For the Quiescent current tables for the ADuM141 and ADuM142 the Test Conditions for the ADuM140 is correct, the ADuM141 and ADuM142 Conditions need to be changed to match the ADuM140. We will change this when we next revise the datasheet.
