... Care should be taken in the layout of such traces to avoid this possibility. POWER CONSUMPTION The supply current at a given channel of the ADuM1210 isolator is a function of the supply voltage, the channel data rate, and the channel output load. For each input channel, the supply current is given by ...

... ADuM1210 In the case of unipolar voltage, the stress on the insulation is significantly lower. This allows operation at higher working voltages while still achieving a 50-year service life. The working voltages listed in Table 10 can be applied while main- taining the 50-year minimum lifetime provided the voltage conforms to either the unipolar voltage case ...
