... APPLICATION INFORMATION PC BOARD LAYOUT The ADuM1100 digital isolator requires no external interface circuitry for the logic interfaces. A bypass capacitor is recom- mended at the input and output supply pins. The input bypass capacitor can conveniently be connected between Pin 3 and Pin 4 (see Figure 13). Alternatively, the bypass capacitor can be located between Pin 1 and Pin 4 ...

... The limitation on the magnetic field immunity of the ADuM1100 is set by the condition in which induced voltage in = 3.3 V and 5 V) the transformer’s receiving coil is sufficiently large to either falsely set or reset the decoder. The analysis that follows defines the conditions under which this can occur. The 3.3 V operating condition of the ADuM1100 is examined because it represents the most susceptible mode of operation ...

... Care should be taken in the layout of such traces to avoid this possibility. POWER CONSUMPTION The supply current of the ADuM1100 isolator is a function of the supply voltage, the input data rate, and the output load. The input supply current is given by I ...
