Using multiple ADM2687 in a row on a single circuit board

Hello, 

Based on experiments with using multiple (2) devices with integrated isoPower devices, individual shield should not be necessary as mutual interference is not an issue between devices. The use of system shielding and embedded stitching capacitance will help to mitigate against EM radiation to meet regulation standards. 

The application note AN-0971 includes some details, see specifically the section on Input-to-Output stitching. With the ADM2687E an embedded stitching capacitor using overlapping PCB planes is the most effective technique. If reinforced insulation is required, the floating capacitive structure is recommended.
