Figure 33. AMC1200 Layout Recommendation
To maintain the isolation barrier and the high CMTI of the device, the distance between the high-side ground (GND1) and the low-side ground (GND2)
should be kept at maximum; that is, the entire area underneath the device should be kept free of any conducting materials.
