GENERAL DESCRIPTION
The ADuM240x1 are 4-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.
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.
Furthermore, iCoupler devices run at one-tenth to one-sixth
the power of optocouplers at comparable signal data rates.
The ADuM240x isolators provide four independent isolation
channels in a variety of channel configurations and data rates (see
the Ordering Guide). The ADuM240x models operate with the
supply voltage of 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 ADuM240x provide low pulse width distortion (<2 ns
for CRWZ grade) and tight channel-to-channel matching (<2 ns
for CRWZ grade). The ADuM240x isolators have a patented
refresh feature that ensures dc correctness in the absence of input
logic transitions and during power-up/power-down conditions

All voltages are relative to their respective ground.
Supply current values are for all four channels combined 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 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 ADuM2400/ADuM2401/ADuM2402 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 per channel supply current for a
given data rate.

Supply current values are for all four channels combined 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 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 ADuM2400/ADuM2401/ADuM2402 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 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 > 0.8VDD2. 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 per channel supply current for a
given data rate.

APPLICATION INFORMATION
PC BOARD LAYOUT
DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY
The ADuM240x 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
be considered unless the ground pair on each package side are
connected close to the package.
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 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 without power or nonfunctional; in which
case, the isolator output is forced to a default state (see Table 11)
by the watchdog timer circuit.

The limitation on the ADuM240x’s magnetic field immunity is
set by the condition in which induced voltage in the transformer’s
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
ADuM240x is examined because it represents the most
susceptible mode of operation.

Figure 17. Recommended Printed Circuit Board Layout
In applications involving high common-mode transients, 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.
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)Σ∏rn2; 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.
50%
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 input signal’s timing is preserved.
Channel-to-channel matching refers to the maximum amount
the propagation delay differs among channels within a single
ADuM240x component.
Propagation delay skew refers to the maximum amount the
propagation delay differs among multiple ADuM240x components
operated under the same conditions.

Given the geometry of the receiving coil in the ADuM240x and

ADuM2400/ADuM2401/ADuM2402
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
ADuM240x transformers. Figure 20 expresses these allowable
current magnitudes as a function of frequency for selected
distances. As can be seen, the ADuM240x 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, place a 0.5 kA current 5 mm away from the
ADuM240x to affect the component’s operation.
For each output channel, the supply current is given by:

Various Current-to-ADuM240x Spacings
The supply current at a given channel of the ADuM240x 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 ≤ 0.5fr
IDDI = IDDI (D) × (2f − fr) + IDDI (Q)
f > 0.5fr
IDDO = IDDO (Q)
f ≤ 0.5fr
-3
IDDO = (IDDO (D) + (0.5 × 10 × CLVDDO) × (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 8 and Figure 9 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 the total IDD1 and IDD2 as a function of
data rate for the ADuM2400/ADuM2401/ ADuM2402 channel
configurations.
Note that at combinations of strong magnetic field and high
frequency, any loops formed by printed circuit board traces
could 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.

Data Sheet
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.
The insulation lifetime of the ADuM240x 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 Analog Devices recommended maximum working
voltage.
RATED PEAK VOLTAGE
05007-021
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 the 50-year service life voltage.
Operation at these high working voltages can lead to shortened
insulation life in some cases.
0V
Figure 21. Bipolar AC Waveform
RATED PEAK VOLTAGE
05007-022
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 ADuM240x.
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 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 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 10.
