... PCB LAYOUT The ADuM5401/ADuM5402/ADuM5403/ADuM5404 digital isolators with 0.5 W isoPower integrated dc-to-dc converters require no external interface circuitry for the logic interfaces. Power supply bypassing is required at the input and output supply pins (see Figure 23). Note that a low ESR bypass capacitor is required between Pin 1 and Pin 2, as close to the chip pads as possible ...
