Data Sheet
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
ADuM2400/ADuM2401/ADuM2402
POWER CONSUMPTION
The supply current at a given channel of the ADuM240x isolator is
a function of the supply voltage, the data rate of the channel,
and the output load of the channel.
For each input channel, the supply current is given by:
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 away from the
ADuM240x transformers. Figure 20 expresses these allowable
I DDI = I DDI (Q)
I DDI = I DDI (D) × (2 f ? f r ) + I DDI (Q)
For each output channel, the supply current is given by:
I DDO = I DDO (Q)
f ≤ 0.5 f r
f > 0.5 f r
f ≤ 0.5 f r
I DDO = ( I DDO (D) + (0.5 × 10 × C L V DDO ) × (2 f ? f r ) + I DDO (Q)
current magnitudes as a function of frequency for selected
distances. As can be seen, the ADuM240x is immune and can
be affected only by extremely large currents operated at high
frequency and very close to the component. For the 1 MHz
example noted, place a 0.5 kA current 5 mm away from the
ADuM240x to affect the component’s operation.

where:
I DDI (D) , I DDO (D) are the input and output dynamic supply currents
per channel (mA/Mbps).
C L is the output load capacitance (pF).
V DDO is the output supply voltage (V).
f is the input logic signal frequency (MHz, half of the input data
rate, NRZ signaling).
f r is the input stage refresh rate (Mbps).
I DDI (Q) , I DDO (Q) are the specified input and output quiescent
supply currents (mA).
To calculate the total I DD1 and I DD2 , the supply currents for each
input and output channel corresponding to I DD1 and I DD2 are
calculated and totaled. Figure 8 and Figure 9 provide per channel
supply currents as a function of data rate for an unloaded output
condition. Figure 10 provides per channel supply current as a

through Figure 15 provide the total I DD1 and I DD2 as a function of
data rate for the ADuM2400/ADuM2401/ADuM2402 channel
configurations.
Note that at combinations of strong magnetic field and high
frequency, any loops formed by printed circuit board traces
could induce sufficiently large error voltages to trigger the
thresholds of succeeding circuitry. Care should be taken in
the layout of such traces to avoid this possibility.
