Qualified for automotive applications
The ADuM340xW1 are 4-channel digital isolators based on the
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.
iCoupler devices remove the design difficulties commonly
associated with optocouplers. 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 the power
of optocouplers at comparable signal data rates.
The ADuM340xW isolators provide four independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). All models of the ADuM340xW
provide operation from 3.135 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage level translation function across the isolation barrier. The
ADuM340xW isolators have a patented refresh feature that ensures
dc correctness in the absence of input logic transitions and
during power-up/power-down conditions.
The ADuM340xW isolators contain various circuit and layout
changes to provide increased capability relative to system-level IEC
61000-4-x testing (ESD/burst/surge). The precise capability in
these tests is strongly determined by the design and layout of
the user’s board or module. For more information, see the
AN-793 Application Note, ESD/Latch-Up Considerations with
iCoupler Isolation Products.

APPLICATION INFORMATION
The ADuM3400W/ADuM3401W/ADuM3402W digital
isolator requires 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.
While the ADuM3400W/ADuM3401W/ADuM3402W
improve system-level ESD reliability, they are no substitute for a
robust system-level design. See the AN-793 Application Note,
ESD/Latch-Up Considerations with iCoupler Isolation Products
for detailed recommendations on board layout and system-level
design.
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 low output can differ from the propagation
delay to a logic high.

PC BOARD LAYOUT
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.
SYSTEM-LEVEL ESD CONSIDERATIONS AND
ENHANCEMENTS
Pulse width distortion is the maximum difference between
these two propagation delay values and is an indication of how
accurately the input signal’s timing is preserved.
Channel-to-channel matching refers to the maximum amount
the propagation delay differs between channels within a single
ADuM3400W/ADuM3401W/ADuM3402W component.
Propagation delay skew refers to the maximum amount the
propagation delay differs between multiple ADuM3400W/
ADuM3401W/ADuM3402W components operating under the
same conditions.
DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY
System-level ESD reliability (for example, per IEC 61000-4-x) is
highly dependent on system design, which varies widely by
application. The ADuM3400W/ADuM3401W/ADuM3402W
incorporate many enhancements to make ESD reliability less
dependent on system design. The enhancements include:
ESD protection cells added to all input/output interfaces.
Key metal trace resistances reduced using wider geometry
and paralleling of lines with vias.
The SCR effect inherent in CMOS devices minimized by
use of guarding and isolation technique between PMOS
and NMOS devices.
Areas of high electric field concentration eliminated using
45° corners on metal traces.
Supply pin overvoltage prevented with larger ESD clamps
between each supply pin and its respective ground.
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 20) by the
watchdog timer circuit.
The limitation on the magnetic field immunity of the
ADuM3400W/ADuM3401W/ADuM3402W is set by the
condition in which induced voltage in the receiving coil of the
transformer is sufficiently large to either falsely set or reset the
decoder. The following analysis defines the conditions under
which this can occur. The 3.3 V operating condition of the
ADuM3400W/ADuM3401W/ADuM3402W is examined
because it represents the most susceptible mode of operation.

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 ADuM3400W/
ADuM3401W/ADuM3402W and an imposed requirement that
the induced voltage be at most 50% of the 0.5 V margin at the
decoder, a maximum allowable magnetic field is calculated as
shown in Figure 19.

The pulses at the transformer output have an amplitude greater

establishing a 0.5 V margin in which induced voltages can be
tolerated. The voltage induced across the receiving coil is given by

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.

Figure 19. Maximum Allowable External Magnetic Flux Density
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, which 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.
The preceding magnetic flux density values correspond to
specific current magnitudes at given distances from the
ADuM3400W/ADuM3401W/ADuM3402W transformers.
Figure 20 expresses these allowable current magnitudes as a
function of frequency for selected distances. As shown, the
ADuM3400W/ADuM3401W/ADuM3402W 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 noted, one would have to place a 0.5 kA
current 5 mm away from the ADuM3400W/ADuM3401W/
ADuM3402W to affect the operation of the component.

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).

ADuM3400W/ADuM3401W/ADuM3402W
To calculate the total IDD1 and IDD2 supply current, the supply
currents for each input and output channel corresponding to
VDD1 and VDD2 are calculated and totaled. Figure 8 provides the
per-channel input supply current as a function of the data rate.
Figure 9 and Figure 10 provide the per-channel supply output
current as a function of the data rate for an unloaded output
condition and for a 15 pF output condition, respectively. Figure 11
through Figure 15 provide the total VDD1 and VDD2 supply
current as a function of the data rate for ADuM3400W/
ADuM3401W/ADuM3402W channel configurations.
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 19 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 19.
INSULATION LIFETIME
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.

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
Figure 21 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 the 50-year service life
voltage. Operation at these high working voltages can lead to
shortened insulation life in some cases.

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 ADuM3400W/
ADuM3401W/ADuM3402W.
0V
The insulation lifetime of the ADuM3400W/ADuM3401W/
ADuM3402W 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.
Bipolar ac voltage is the most stringent environment. The goal
of a 50-year operating lifetime under the ac bipolar condition
determines the recommended maximum working voltage of
Analog Devices.
