Hi,

I received the following question from my customer.

The vertical axis of fig7 is Input bandwidth.

How is this input bandwidth defined?

Hi Kuramochi,

As I suspected, the 60kHz bandwith is related to the 3rd low-pass filter in the AMC1200. It's not really a input referred specification so I'll see what we can do to modify the vertical axis label in the datasheet.
