While sensing the 230V single-phase ac voltage as shown in the attached schematic, can we use the direct connection of the AC power supply Neutral to the GND1 on the high side of the AMC1350. If it is not recommended can you please suggest us the correct way to give the grounding. The +5V VDD1 in the schematic is taken from the one of the winding of flyback auxiliary supply where the ground is also connected to AC supply Neutral.
