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.

POWER CONSUMPTION

0.100

The supply current at a given channel of the ADuM130x isola-

tor is a function of the supply voltage, the channel’s data rate,

and the channel’s output load.

MAGNETIC FIELD FREQUENCY (Hz)

Figure 16. Maximum Allowable External Magnetic Flux Density

I_DDI= I_{DDI (D)}× (2f – f_r) + I_{DDI (Q)}

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.

For each output channel, the supply current is given by

I_DDO= I_{DDO (Q)}f ≤ 0.5f_r

_DDO= (I_{DDO (D)}+ (0.5 × 10⁻³) × C_LV_DDO) × (2f – f_r) + I_{DDO (Q)}

f > 0.5f_r

where:

I_{DDI (D)}, I_{DDO (D)}are the input and output dynamic supply currents

per channel (mA/Mbps).

The preceding magnetic flux density values correspond to

specific current magnitudes at given distances from the

ADuM130x transformers. Figure 17 expresses these allowable

current magnitudes as a function of frequency for selected

distances. As seen, the ADuM130x is extremely immune and

can be affected only by extremely large currents operated at

high frequency, very close to the component. For the 1 MHz

example, one would have to place a 0.5 kA current 5 mm away

from the ADuM130x to affect the component’s operation.

C_Lis output load capacitance (pF).

_DDOis the output supply voltage (V).

f is the input logic signal frequency (MHz, half of the input data

rate, NRZ signaling).

f_ris the input stage refresh rate (Mbps).

I_{DDI (Q)}, I_{DDO (Q)}are the specified input and output quiescent sup-

ply currents (mA).

To calculate the total I_DD1and I_DD2supply current, the supply

currents for each input and output channel corresponding to

I_DD1and I_DD2are 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 condition. Figure 9 through Figure 12 provide total

I_DD1and I_DD2supply current as a function of data rate for

ADuM1300/ADuM1301 channel configurations.
