ADuM1300/ADuM1301
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 occurs during a transmitted pulse
(and has the worst-case polarity), it reduces the received pulse
Data Sheet
POWER CONSUMPTION
The supply current at a given channel of the ADuM130x
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
from >1.0 V to 0.75 V—still well above the 0.5 V sensing
threshold of the decoder.
I DDI = I DDI ( Q )
I DDI = I DDI ( D ) × (2 f ? f r ) + I DDI (Q)
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 )
The preceding magnetic flux density values correspond to
specific current magnitudes at given distances from the
ADuM130x transformers. Figure 17 shows these allowable
current magnitudes as a function of frequency for selected
distances. The ADuM130x is extremely immune and can be
affected only by extremely large currents operated at a high
frequency very close to the component. For the 1 MHz example
noted, one would have to place a 0.5 kA current 5 mm away
from the ADuM130x to affect the operation of the component.

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
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); it is half of the input
data rate expressed in units of Mbps.
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 V DD1 and V DD2 supply current, the supply
currents for each input and output channel corresponding to
V DD1 and V DD2 are calculated and totaled. Figure 6 and Figure 7
provide per-channel supply currents as a function of data rate
for an unloaded output condition. Figure 8 provides per-channel
supply current as a function of data rate for a 15 pF output

for Various Current-to-ADuM130x Spacings
V DD2 supply current as a function of data rate for ADuM1300/
ADuM1301 channel configurations.
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.
