Data Sheet
Given the geometry of the receiving coil in the ADuM3200 /
ADuM3201 and an imposed requirement that the induced
voltage is at most 50% of the 0.5 V margin at the decoder, a
maximum allowable magnetic field is calculated, as shown in
Figure 13.

ADuM3200/ADuM3201
The preceding magnetic flux density values correspond to
specific current magnitudes at given distances away from the
ADuM3200 / ADuM3201 transformers. Figure 14 expresses
these allowable current magnitudes as a function of frequency
for selected distances. As seen, the ADuM3200 / ADuM3201 are
extremely immune and can be affected only by extremely large
currents operated at high frequency and very close to the com-
ponent. For the 1 MHz example, one would have to place a 0.5 kA
current 5 mm away from the ADuM3200 / ADuM3201 to affect
the component’s operation.

For example, at a magnetic field frequency of 1 MHz, the

DISTANCE = 5mm
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 had 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.

Current-to- ADuM3200 / ADuM3201 Spacings
Note that at combinations of strong magnetic fields and high
frequencies, any loops formed by printed circuit board traces
could induce sufficiently large error voltages to trigger the
threshold of succeeding circuitry. Care should be taken in
the layout of such traces to avoid this possibility.
