I'm looking for the value of the leakage current of the ADuM4160.
For medical devices this value is very important but I didn't find any information in the datasheet or the homepage of Analog Devices.
Hello Medical Engineer,
There are two types of leakage to worry about, and they can be calculated with the information in Table 2.
DC leakage will be leakage due to the resistance of the insulation materials. The reality is that this is essentially 0 but the real world allows some leakage due to surface contamination and humidity etc. We guarantee that the DC resistance is greater than 1Gohm. The reality is that it is much higher but not terribly useful in the real world.
AC leakage will be through the parasitic capacitance in the iCoupler. Table 2 shows the capacitance to be 2.2pF, so you can calculate the leakage for the frequency and voltage that applies to your application.
We verify that there are no gross leakage paths in the 1 second isolation test that each part goes through. At 60Hz, and 6000V the leakage through the part is <10uA, as stated in the footnote to Table 3.
I hope this helps.
