Qualified for automotive applications
The ADuM3210/ADuM3211 are dual-channel, digital isolators
based on Analog Devices, Inc., iCoupler® technology. Combining
high speed CMOS and monolithic transformer technology, this
isolation component provides outstanding performance characteristics superior to alternatives such as optocoupler devices.
APPLICATIONS
Size-critical multichannel isolation
SPI interface/data converter isolation
RS-232/RS-422/RS-485 transceiver isolation
Digital field bus isolation
Gate drive interfaces
Hybrid electric vehicles, battery monitor, and motor drive
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 the power of optocouplers at
comparable signal data rates.
The ADuM3210/ADuM3211 isolators provide two independent
isolation channels in two channel configurations with data rates
up to 25 Mbps (see the Ordering Guide). They operate with 3.3 V
or 5 V supply voltages on either side, providing compatibility
with lower voltage systems as well as enabling voltage translation
functionality across the isolation barrier. The ADuM3210/
ADuM3211 isolators have a default output low characteristic in
comparison to the ADuM3200/ ADuM3201 models that have a
default output high characteristic. ADuM3210W and ADuM3211W
are automotive grade versions qualified for 125°C operation.
In comparison to the ADuM120x isolator, the ADuM3210/
ADuM3211 isolators contain various circuit and layout changes
providing increased capability relative to system-level IEC 61000-4-x
testing (ESD, burst, and surge). The precise capability in these tests
for either the ADuM120x or ADuM3210/ADuM3211 products 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.

APPLICATIONS INFORMATION
PC BOARD LAYOUT
DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY
The ADuM3210/ADuM3211 digital isolators require no external
interface circuitry for the logic interfaces. Power supply bypassing
is strongly recommended at the input and output supply pins.
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.
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 of more than 2 μs at the input, 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 for more than approximately 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 34
and Table 35) by the watchdog timer circuit.
SYSTEM-LEVEL ESD CONSIDERATIONS AND
ENHANCEMENTS
System-level ESD reliability (for example, per IEC 61000-4-x)
is highly dependent on system design, which varies widely by
application. The ADuM3210/ADuM3211 incorporate many
enhancements to make ESD reliability less dependent on system
design. The enhancements include:
•
•
•
•
•
ESD protection cells were 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 is minimized
by use of a guarding and isolation technique between the
PMOS and NMOS devices.
Areas of high electric field concentration are eliminated
using 45° corners on metal traces.
Supply pin overvoltage is prevented with larger ESD
clamps between each supply pin and its respective ground.
The ADuM3210/ADuM3211 are immune to external magnetic
fields. The limitation on the ADuM3210/ADuM3211 magnetic
field immunity is set by the condition in which induced voltage
in the transformer receiving coil is sufficiently large to either
falsely set or reset the decoder. The following analysis defines
the conditions under which this can occur. The 3 V operating
condition of the ADuM3210/ADuM3211 is examined because
it represents the most susceptible mode of operation.
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,
therefore 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) ∑π rn2, n = 1, 2, ... , N
While the ADuM3210/ADuM3211 improve system-level ESD
reliability, they are no substitute for a robust system-level
design. For detailed recommendations on board layout and
system-level design, see the AN-793 Application Note,
ESD/Latch-Up Considerations with iCoupler Isolation Products.
where:
β is the 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).
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 output.
Given the geometry of the receiving coil in the ADuM3210/
ADuM3211 and an imposed requirement that the induced
voltage is at most 50% of the 0.5 V margin at the decoder, a
maximum allowable magnetic field is calculated as shown in
Figure 13.

Figure 12. Propagation Delay Parameters
Pulse width distortion is the maximum difference between
these two propagation delay values and is an indication of
how accurately the input signal timing is preserved.
Channel-to-channel matching refers to the maximum amount
that the propagation delay differs between channels within a
single ADuM3210/ADuM3211 component.
Propagation delay skew refers to the maximum amount that
the propagation delay differs between multiple ADuM3210/
ADuM3211 components operating under the same conditions.

ADuM3210/ADuM3211
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 had the worst-case polarity), it would reduce the
received pulse from >1.0 V to 0.75 V, which is still well above
the 0.5 V sensing threshold of the decoder.
POWER CONSUMPTION
The preceding magnetic flux density values correspond to
specific current magnitudes at given distances away from the
ADuM3210/ADuM3211 transformers. Figure 14 expresses
these allowable current magnitudes as a function of frequency
for selected distances. As shown, the ADuM3210/ADuM3211
are immune and can be affected only by extremely large currents
operated at a high frequency and very close to the component.
For the 1 MHz example, a 0.5 kA current would have to be placed
5 mm away from the ADuM3210/ADuM3211 to affect the
operation of the component.

IDDI (D), IDDO (D) are the input and output dynamic supply currents
per channel (mA/Mbps).
IDDI (Q), IDDO (Q) are the specified input and output quiescent

CL is the output load capacitance (pF).
VDDO is the output supply voltage (V).
f is the input logic signal frequency (MHz, half of the input data
rate, NRZ signaling).
fr is the input stage refresh rate (Mbps).
To calculate the total IDD1 and IDD2 supply current, the supply
currents for each input and output channel corresponding to
IDD1 and IDD2 are calculated and totaled.

The supply current at a given channel of the ADuM3210/
ADuM3211 isolator is a function of the supply voltage, channel
data rate, and channel output load.
Figure 14. Maximum Allowable Current for Various
Current-to-ADuM3210/-ADuM3211 Spacings
Figure 6 provides the input supply currents per channel as a
function of data rate. Figure 7 and Figure 8 provide the output
supply currents per channel as a function of data rate for an
unloaded output condition and for a 15 pF output condition,
respectively. Figure 9 through Figure 11 provide total IDD1 and
IDD2 supply current as a function of data rate for the ADuM3210
and ADuM3211 channel configurations.
Note that at combinations of strong magnetic fields and high
frequencies, any loops formed by the printed circuit board
(PCB) traces may induce sufficiently large error voltages to
trigger the threshold of succeeding circuitry. Care should be
taken in the layout of such traces to avoid this possibility.

ADuM3210/ADuM3211
Data Sheet
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 31 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.
Note that the voltage presented in Figure 16 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.
The insulation lifetime of the ADuM3210/ADuM3211 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 15, Figure 16, and Figure 17 illustrate these different
isolation voltage waveforms.
A bipolar ac voltage environment is the most stringent. The
goal of a 50-year operating lifetime under the ac bipolar
condition determines the Analog Devices recommended
maximum working voltage.
RATED PEAK VOLTAGE
06866-012
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 ADuM3210/ADuM3211.
In the case of unipolar ac or dc voltage, the stress on the insulation
is significantly lower. This allows operation at higher working
voltages while still achieving a 50-year service life. The working
voltages listed in Table 31 can be applied while maintaining the
50-year minimum lifetime provided that the voltage conforms
to either the unipolar ac or dc voltage cases. Any cross-insulation
voltage waveform that does not conform to Figure 16 or Figure 17
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 31.
