The Layout Example section provides a layout recommendation detailing the placement of the critical decoupling and filter capacitors. Place decoupling and filter capacitors as close as possible to the AMC0386-Q1 input pins.

Place a guard ring around the SNSP pin and connect the guard ring to AGND. The guard ring prevents leakage currents from forming a parallel current path between HVIN and SNSP. The guard ring is partially routed underneath the device, reducing the clearance distance between the high-voltage and low-voltage side. Place a keep-out zone around pins 7 and 8 (neither pins have internal connection) to recover the full clearance distance of >8mm.

To maximize the creepage distance between the high-voltage and low-voltage side, place another keep-out zone around pin 15 as illustrated in the recommended layout.
