The ADuM1400/ADuM1401/ADuM1402 1 are quad-channel
digital isolators based on Analog Devices, Inc., iCoupler®
technology. Combining high speed CMOS and monolithic air
core transformer technology, these isolation components provide
outstanding performance characteristics superior to alternatives,
such as optocoupler devices.
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with optocouplers. The typical optocoupler concerns regarding uncertain
current transfer ratios, nonlinear transfer functions, and
temperature and lifetime effects are eliminated with the simple
iCoupler digital interfaces and stable performance characteristics.
The need for external drivers and other discrete components is
eliminated with these iCoupler products. Furthermore, iCoupler
devices consume one tenth to one sixth of the power of
optocouplers at comparable signal data rates.
The ADuM1400/ADuM1401/ADuM1402 isolators provide four
independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). All models
operate with the supply voltage on either side ranging from
2.7 V to 5.5 V, providing compatibility with lower voltage
systems as well as enabling a voltage translation functionality
across the isolation barrier. In addition, the ADuM1400/
ADuM1401/ADuM1402 provide low pulse width distortion
( 0.8 VDD2. CML is the maximum common-mode voltage slew rate
that can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient
magnitude is the range over which the common mode is slewed.

Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 8 through Figure 10 for information
on per-channel supply current for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating the per-channel supply current
for a given data rate.

All voltages are relative to their respective ground.
The supply current values for all four channels are combined when running at identical data rates. Output supply current values are specified with no output load
present. The supply current associated with an individual channel operating at a given data rate may be calculated as described in the Power Consumption section.
See Figure 8 through Figure 10 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 11 through
Figure 15 for total VDD1 and VDD2 supply currents as a function of data rate for ADuM1400/ADuM1401/ADuM1402 channel configurations.
3
The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed.
4
The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed.
5
tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is
measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal.
6
tPSK is the magnitude of the worst-case difference in tPHL or tPLH that is measured between units at the same operating temperature, supply voltages, and output load
within the recommended operating conditions.
7
Codirectional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of
the isolation barrier. Opposing-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with
inputs on opposing sides of the isolation barrier.
8
CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD2. CML is the maximum common-mode voltage slew rate
that can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient
magnitude is the range over which the common mode is slewed.

All voltages are relative to their respective ground.
The supply current values for all four channels are combined when running at identical data rates. Output supply current values are specified with no output load
present. The supply current associated with an individual channel operating at a given data rate may be calculated as described in the Power Consumption section.
See Figure 8 through Figure 10 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 11 through
Figure 15 for total VDD1 and VDD2 supply currents as a function of data rate for ADuM1400W/ADuM1401W/ADuM1402W channel configurations.
3
The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed.
4
The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed.
5
tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is
measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal.
6
tPSK is the magnitude of the worst-case difference in tPHL or tPLH that is measured between units at the same operating temperature, supply voltages, and output load
within the recommended operating conditions.
7
Codirectional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of
the isolation barrier. Opposing-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with
inputs on opposing sides of the isolation barrier.
8
CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD2. CML is the maximum common-mode voltage slew rate
that can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient
magnitude is the range over which the common mode is slewed.
9
Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 8 through Figure 10 for information
on per-channel supply current for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating the per-channel supply current
for a given data rate.

Figure 15 for total VDD1 and VDD2 supply currents as a function of data rate for ADuM1400W/ADuM1401W/ADuM1402W channel configurations.
3
The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed.
4
The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed.
5
tPHL propagation delay is measured from the 50% level of the falling edge of the VIx signal to the 50% level of the falling edge of the VOx signal. tPLH propagation delay is
measured from the 50% level of the rising edge of the VIx signal to the 50% level of the rising edge of the VOx signal.
6
tPSK is the magnitude of the worst-case difference in tPHL or tPLH that is measured between units at the same operating temperature, supply voltages, and output load
within the recommended operating conditions.
7
Codirectional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of
the isolation barrier. Opposing-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with
inputs on opposing sides of the isolation barrier.
8
CMH is the maximum common-mode voltage slew rate that can be sustained while maintaining VO > 0.8 VDD2. CML is the maximum common-mode voltage slew rate
that can be sustained while maintaining VO < 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges. The transient
magnitude is the range over which the common mode is slewed.
9
Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 8 through Figure 10 for information
on per-channel supply current for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating the per-channel supply current
for a given data rate.

The ADuM1400/ADuM1401/ADuM1402 digital isolators
require no external interface circuitry for the logic interfaces.
Power supply bypassing is strongly recommended at the input
and output supply pins (see Figure 17). Bypass capacitors are
most conveniently connected between Pin 1 and Pin 2 for VDD1
and between Pin 15 and Pin 16 for VDD2. The capacitor value
should be between 0.01 μF and 0.1 μF. The total lead length
between both ends of the capacitor and the input power supply
pin should not exceed 20 mm. Bypassing between Pin 1 and Pin
8 and between Pin 9 and Pin 16 should also be considered,
unless the ground pair on each package side is connected close
to the package.
Figure 17. Recommended Printed Circuit Board Layout
In applications involving high common-mode transients, care
should be taken to ensure that board coupling across the isolation
barrier is minimized. Furthermore, the board layout should be
designed such that any coupling that does occur equally affects
all pins on a given component side. Failure to ensure this could
cause voltage differentials between pins exceeding the Absolute
Maximum Ratings of the device, thereby leading to latch-up or
permanent damage.
See the AN-1109 Application Note for board layout guidelines.
PROPAGATION DELAY-RELATED PARAMETERS
Propagation delay is a parameter that describes the time it takes
a logic signal to propagate through a component. The propagation
delay to a Logic 0 output may differ from the propagation delay
to a Logic 1 output.
50%
The pulses at the transformer output have an amplitude greater
than 1.0 V. The decoder has a sensing threshold at about 0.5 V, thus
establishing a 0.5 V margin in which induced voltages can be
tolerated. The voltage induced across the receiving coil is given by
V = (−dβ/dt)∑∏rn2; n = 1, 2, … , N
where:
β is magnetic flux density (gauss).
N is the number of turns in the receiving coil.
rn is the radius of the nth turn in the receiving coil (cm).
Given the geometry of the receiving coil in the ADuM1400/
ADuM1401/ADuM1402 and an imposed requirement that the
induced voltage be 50% at most of the 0.5 V margin at the
decoder, a maximum allowable magnetic field is calculated as
shown in Figure 19.
50%
Figure 18. Propagation Delay Parameters
Pulse width distortion is the maximum difference between
these two propagation delay values and is an indication of how
accurately the timing of the input signal is preserved.
Channel-to-channel matching refers to the maximum amount
the propagation delay differs between channels within a single
ADuM1400/ADuM1401/ADuM1402 component.
Propagation delay skew refers to the maximum amount the
propagation delay differs between multiple ADuM1400/
ADuM1401/ADuM1402 components operating under the same
conditions.

The limitation on the magnetic field immunity of the ADuM1400/
ADuM1401/ADuM1402 is set by the condition in which induced
voltage in the receiving coil of the transformer is sufficiently large
enough to either falsely set or reset the decoder. The following
analysis defines the conditions under which this may occur. The
3 V operating condition of the ADuM1400/ADuM1401/
ADuM1402 is examined because it represents the most susceptible
mode of operation.

Positive and negative logic transitions at the isolator input
cause narrow (~1 ns) pulses to be sent to the decoder via the
transformer. The decoder is bistable and is, therefore, either set
or reset by the pulses, indicating input logic transitions. In the
absence of logic transitions at the input for more than ~1 μs, a
periodic set of refresh pulses indicative of the correct input state
are sent to ensure dc correctness at the output. If the decoder
receives no internal pulses of more than about 5 μs, the input
side is assumed to be unpowered or nonfunctional, in which
case the isolator output is forced to a default state (see Table 15)
by the watchdog timer circuit.

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.
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.

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
IDDI = IDDI (Q)
f ≤ 0.5 fr
IDDI = IDDI (D) × (2f − fr) + IDDI (Q)
f > 0.5 fr
For each output channel, the supply current is given by
IDDO = IDDO (Q)
f ≤ 0.5 fr
IDDO = (IDDO (D) + (0.5 × 10 ) × CL × VDDO) × (2f − fr) + IDDO (Q)
f > 0.5 fr
−3
where:
IDDI (D), IDDO (D) are the input and output dynamic supply currents
per channel (mA/Mbps).
CL is the output load capacitance (pF).
VDDO 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.
fr is the input stage refresh rate (Mbps).
IDDI (Q), IDDO (Q) are the specified input and output quiescent
supply currents (mA).
To calculate the total VDD1 and VDD2 supply current, the supply
currents for each input and output channel corresponding to
VDD1 and VDD2 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 perchannel supply current as a function of data rate for a 15 pF
output condition. Figure 11 through Figure 15 provide total
VDD1 and VDD2 supply current as a function of data rate for
ADuM1400/ADuM1401/ADuM1402 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.

ADuM1400/ADuM1401/ADuM1402
All insulation structures eventually break down when subjected
to voltage stress over a sufficiently long period. The rate of
insulation degradation is dependent on the characteristics of
the voltage waveform applied across the insulation. In addition
to the testing performed by the regulatory agencies, Analog
Devices carries out an extensive set of evaluations to determine
the lifetime of the insulation structure within the ADuM1400/
ADuM1401/ADuM1402.
Analog Devices performs accelerated life testing using voltage
levels higher than the rated continuous working voltage. Acceleration factors for several operating conditions are determined.
These factors allow calculation of the time to failure at the actual
working voltage. The values shown in Table 14 summarize the
peak voltage for 50 years of service life for a bipolar ac operating
condition and the maximum CSA/VDE approved working
voltages. In many cases, the approved working voltage is higher
than a 50-year service life voltage. Operation at these high working
voltages can lead to shortened insulation life in some cases.
In the case of unipolar ac or dc voltage, the stress on the insulation
is significantly lower, which allows operation at higher working
voltages while still achieving a 50-year service life. The working
voltages listed in Table 14 can be applied while maintaining the
50-year minimum lifetime, provided the voltage conforms to either
the unipolar ac or dc voltage cases. Any cross-insulation voltage
waveform that does not conform to Figure 22 or Figure 23 should
be treated as a bipolar ac waveform, and its peak voltage should
be limited to the 50-year lifetime voltage value listed in Table 14.
Note that the voltage presented in Figure 22 is shown as sinusoidal
for illustration purposes only. It is meant to represent any voltage
waveform varying between 0 V and some limiting value. The
limiting value can be positive or negative, but the voltage cannot
cross 0 V.

Bipolar ac voltage is the most stringent environment. The goal

The insulation lifetime of the ADuM1400/ADuM1401/
ADuM1402 depends on the voltage waveform type imposed
across the isolation barrier. The iCoupler insulation structure
degrades at different rates depending on whether the waveform
is bipolar ac, unipolar ac, or dc. Figure 21, Figure 22, and Figure 23
illustrate these different isolation voltage waveforms, respectively.
