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.
