The ADuM220x 1 are 2-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 that
are superior to alternatives such as optocoupler devices.
APPLICATIONS
General-purpose, high voltage, multichannel isolation
Medical equipment
Power supplies
RS-232/RS-422/RS-485 transceiver isolation
By avoiding the use of LEDs and photodiodes, 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 run at one-tenth to one-sixth
the power of optocouplers at comparable signal data rates.
The ADuM220x isolators provide two independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). The ADuM220x models operate with
the supply voltage of either side ranging from 3.0 V to 5.5 V,
providing compatibility with lower voltage systems as well as
enabling voltage translation functionality across the isolation
barrier. In addition, the ADuM220x provide low pulse width
distortion (<3 ns for BRWZ grade) and tight channel-tochannel matching (<3 ns for BRWZ grade). Unlike other
optocoupler alternatives, the ADuM220x isolators have a
patented refresh feature that ensures dc correctness in the
absence of input logic transitions and during power-up/powerdown conditions.

All voltages are relative to their respective ground.
The supply current values for both 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 can be calculated as described in the Power Consumption section. See
Figure 6 through Figure 8 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 9 through Figure 11
for total IDD1 and IDD2 supply currents as a function of data rate for ADuM2200 and ADuM2201 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 and/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 the signal data rate. See Figure 6 through Figure 8 for
information on per-channel supply current for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating per-channel supply
current for a given data rate.

All voltages are relative to their respective ground.
The supply current values for both 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 can be calculated as described in the Power Consumption section. See
Figure 6 through Figure 8 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 9 through Figure 11
for total IDD1 and IDD2 supply currents as a function of data rate for ADuM2200 and ADuM2201 channel configurations.

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 and/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 the signal data rate. See Figure 6 through Figure 8 for
information on per-channel supply current for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating per-channel supply
current for a given data rate.

APPLICATIONS INFORMATION
PC BOARD LAYOUT
The ADuM220x 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 12). Bypass capacitors are most conveniently connected
between Pin 1 and Pin 3 for VDD1 and between Pin 14 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 3 and Pin 7 and between Pin 9
and Pin 14 should be considered unless the ground pair on each
package side are connected close to the package.

Figure 12. Recommended Printed Circuit Board Layout
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
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 device’s Absolute Maximum Ratings, thereby
leading to latch-up or permanent damage.
V = (−dβ/dt)Σπrn2; n = 1, 2,…, N
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 length of
time it takes for a logic signal to propagate through a component. The propagation delay to a logic low output can differ
from the propagation delay to logic high.
INPUT (VIx)
Given the geometry of the receiving coil in the ADuM220x 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 14.
50%
50%
Figure 13. 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’s timing is preserved.
Channel-to-channel matching refers to the maximum amount
the propagation delay differs among channels within a single
ADuM220x component.
Propagation delay skew refers to the maximum amount the
propagation delay differs among multiple ADuM220x
components operated under the same conditions.

OUTPUT (VOx)
Positive and negative logic transitions at the isolator input cause
narrow (~1 ns) pulses to be sent via the transformer to the
decoder. 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
is 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 without power or nonfunctional;
in which case, the isolator output is forced to a default state (see
Table 11 and Table 12) by the watchdog timer circuit.
The limitation on the ADuM220x magnetic field immunity is
set by the condition in which induced voltage in the transformer receiving coil is large enough 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
ADuM220x is examined because it represents the most susceptible mode of operation.

DC CORRECTNESS AND MAGNETIC FIELD
IMMUNITY
ADuM2200/ADuM2201
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.
POWER CONSUMPTION
The preceding magnetic flux density values correspond to
specific current magnitudes at given distances away from the
ADuM220x transformers. Figure 15 expresses these allowable
current magnitudes as a function of frequency for selected
distances. As can be seen, the ADuM220x is immune and can
be affected only by extremely large currents operated at high
frequency and very close to the component. For the 1 MHz
example noted previously, one would have to place a 0.5 kA current
5 mm away from the ADuM220x to affect operation of the
component.
For each output channel, the supply current is given by

The supply current at a given channel of the ADuM220x
isolator is a function of the supply voltage, the channel’s data
rate, and the channel’s output load.
For each input channel, the supply current is given by
IDDI = IDDI (Q)
f ≤ 0.5fr
IDDI = IDDI (D) × (2f − fr) + IDDI (Q)
f > 0.5fr
IDDO = IDDO (Q)
f ≤ 0.5fr
−3
IDDO = (IDDO (D) + (0.5 × 10 ) × CL × VDDO) × (2f − fr) + IDDO (Q)
f > 0.5fr
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, half of the input data
rate, NRZ signaling).
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 IDD1 and IDD2, the supply currents for
each input and output channel corresponding to IDD1 and IDD2
are calculated and totaled. Figure 6 and Figure 7 provide perchannel 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 11 provide total IDD1 and IDD2
as a function of data rate for ADuM2200/ADuM2201 channel
configurations.
Note that at combinations of strong magnetic field and high
frequency, any loops formed by printed circuit board traces can
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.

Note that the voltage presented in Figure 17 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 ADuM220x 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 16, Figure 17, and Figure 18 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 Analog Devices recommended maximum
working voltage.
In the case of unipolar ac or dc voltage, the stress on the
insulation is significantly lower. This allows operation at higher

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 10 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 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 ADuM220x.
working voltages while still achieving a 50 year service life. The
working voltages listed in Table 10 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 17
or Figure 18 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 10.
