Hi !

 

I have some questions about ADuM140x.

At datasheet RevK , the specification is this.

But at Rev.L , the specification is this.

 

I thought that each parameter are these.

 

And my questions are these.

 

Q1)

Why did ADI change the specifications about insulation?

Especially we want to know why ADI changed "Clearance" and "Creepage".

 

Q2)

We couldn't understand which number is showing for each parameter.

Can you draw ADuM140x package picture and write each parameter to the package picture?

 

Best regards

Kawa
