ADuM3300/ADuM3301
The pulses at the transformer output have an amplitude greater
than 1.0 V The decoder has a sensing threshold at about 0.5 V thus
establishing a 0.5 V margin in which induced voltages can be
tolerated. The voltage induced across the receiving coil is given by

Given the geometry of the receiving coil in the ADuM330x and
an imposed requirement that the induced voltage be at most
50% of the 0.5 V margin at the decoder, a maximum allowable
magnetic field is calculated as shown in Figure 16.

Figure 16. Maximum Allowable External Magnetic Flux Density
For example, at a magnetic field frequency of 1 MHz, the
maximum allowable magnetic field of 0.2 kgauss induces a
voltage of 0.25 V at the receiving coil. This is about 50% of the
sensing threshold and does not cause a faulty output transition.
Similarly, if such an event were to occur during a transmitted
pulse (and was of the worst-case polarity), it would reduce the
received pulse from >1.0 V to 0.75 V—still well above the 0.5 V
sensing threshold of the decoder.
The preceding magnetic flux density values correspond to
specific current magnitudes at given distances from the
ADuM330x transformers. Figure 17 expresses these allowable
current magnitudes as a function of frequency for selected
distances. The ADuM330x is extremely immune and can be
affected only by extremely large currents operated at high
frequency very close to the component (see Figure 17). For the
1 MHz example noted, one would have to place a 0.5 kA current
5 mm away from the ADuM330x to affect the component’s
operation.

Spacings
Note that at combinations of strong magnetic field and high
frequency, any loops formed by printed circuit board traces
could induce error voltages sufficiently large enough to trigger
the thresholds of succeeding circuitry. Care should be taken in
the layout of such traces to avoid this possibility.
