Hello, Benjamin,
Thank you for your prompt reply. But I'm still confusing...
Your answer 1) is same as my suppose 1), isn't it?
and I suppose your answer 1) and 2) are same explain, aren't they?
At the other point of my question, how to check the input signal range to keep data sheet specification ?
Where and how probe to check each absolute value and specification value?
Thank you for your help.
Best regards,
Sofy
