Our customer will use ADM2587 and we reffer AN-1349 of application note.
We have one question.
AN-1349 recommends that Pin11 and Pin14 are connected by PCB trace.
What is the reason which connects Pin11 and Pin14?
We think that Pin11 is GND of Iso DCDC converter and Pin14 is GND of transceiver
from Datasheet figure 2 pin configuration.
We do not understand why their pins must be connected by the PCB trace.
Please let me know your advice.
