Hi !
Q1)
Our customer want to know the supply current.
I already asked about this and you gave me ADuM142's spread sheet.
(ADuM140)Supply current with OOK.
Can you give me the same thing for ADuM140?
Q2)
Also , ADI's newest iCoupler series is very difficult to calculate the supply power.
Do you have any plan to update the datasheet or make a new application note for this?
Best regards
Kawa
Hi Brian-san
Thank you for your reply.
We have not receive these questions from our customer yet.
But I think they will ask this to us in future.
So I am not hurrying that much but if you can help us about this, the information will be very useful.
Kawa-san: I will discuss with the designer and respond back.
Regards, Brian
I understood what you wrote and I think your information is very useful.
If I have more questions about this , I will ask you later .
Kawa-san:
I will show you here the formula for supply current from the designer. I will be away on vacation for 1 week, but since you say it is not urgent perhaps you may ask your follow up questions when I return after August 10th.
