Hi team,

Is the input AMP a fully differential AMP?
My customers are concerned about whether to insert a GND line into the CAN signal line (wire).



Sincerely.
Kengo.

    Kengo,

    This is the same design as any CAN bus receiver, so it will behave the same as a much more simple transceiver, like the TCAN1042-Q1. Can you elaborate on what you mean by insert a GND line into the CAN signal line? If you mean a ground cable in the CAN bus cable harness, this is a standard practice and there won't be any issues. 

    Regards,
