Hello,
For the ADuM140D, I see a quiescent supply current in Table 1, as well as "total" supply current in Table 2. If I want to calculate the total current draw IDD1 or IDD2 for VDD1 and VDD2 supplies, would I go about that by summing the quiescent supply current figure from Table 1 to the "total" supply current figure from Table 2, and then adding in the drive strength of all 4 output pins? I.e., If we are driving all 4 outputs at 5 mA, and switching at 1 Mbps, then is total current draw for VDD2 equal to 4*(5 mA) + 3.7 mA (max spec. from table 2) + 2.92 mA (max spec from table 1)? Or is the quiescent current accounted for in the "Total" supply current figures from table 2?
Best
