ADuM1400/ADuM1401/ADuM1402

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 occurs during a transmitted pulse

(and has the worst-case polarity), it reduces the received pulse

from >1.0 V to 0.75 V—still well above the 0.5 V sensing

threshold of the decoder.

POWER CONSUMPTION

The supply current at a given channel of the ADuM1400/

ADuM1401/ADuM1402 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

I_DDI= I_{DDI (Q)}

f ≤ 0.5 f_r

f > 0.5 f_r

The preceding magnetic flux density values correspond to

specific current magnitudes at given distances from the

ADuM1400/ADuM1401/ADuM1402 transformers. Figure 20

expresses these allowable current magnitudes as a function of

frequency for selected distances. As shown, the ADuM1400/

ADuM1401/ADuM1402 are 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

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

from the ADuM1400/ADuM1401/ADuM1402 to affect the

operation of the component.

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

For each output channel, the supply current is given by

_DDO= I_{DDO (Q)}f ≤ 0.5 f_r

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

f > 0.5 f_r

where:

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

per channel (mA/Mbps).

C_Lis the output load capacitance (pF).

V_DDOis the output supply voltage (V).

1000

f is the input logic signal frequency (MHz); it is half of the input

data rate expressed in units of Mbps.

f_ris the input stage refresh rate (Mbps).

DISTANCE = 1m

100

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

supply currents (mA).

DISTANCE = 100mm

To calculate the total V_DD1and V_DD2supply current, the supply

currents for each input and output channel corresponding to

_DD1and V_DD2are calculated and totaled. Figure 8 and Figure 9

DISTANCE = 5mm

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 function of data rate for a 15 pF

output condition. Figure 11 through Figure 15 provide total

Current-to-ADuM1400/ADuM1401/ADuM1402 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.
