Hi,
I have a customer case that is looking to use the self powered approach for this device, but there is some confision about how all of the GNDs need to be connected. Can you provide guidance on if there are any specific rules to follow?
For example, are COMA and COMD connected to the VD supply GND? Does VD GND need to be capacitively isolated from the loop GND?
If you have an example schematic to follow that would help. I checked the EVM schematic but this looks to be configured in a loop powered config.
Thanks,
Jose
