GENERAL DESCRIPTION
The ADuM120x1 are dual-channel digital isolators based on
the Analog Devices, Inc., iCoupler® technology. Combining
high speed CMOS and monolithic transformer technologies,
these isolation components provide outstanding performance
characteristics superior to alternatives, such as optocouplers.
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with opto-
couplers. The typical optocoupler concerns regarding uncertain
current transfer ratios, nonlinear transfer functions, and temper-
ature 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 ADuM120x isolators provide two independent isolation
channels in a variety of channel configurations and data rates
(see the Ordering Guide). Both parts 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 ADuM120x provide low pulse width distortion
(<3 ns for CR grade) and tight channel-to-channel matching
(<3 ns for CR grade). Unlike other optocoupler alternatives,
the ADuM120x 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 ADuM1200W and ADuM1201W are automotive grade
versions qualified for 125°C operation. See the Automotive
Products section for more information.

2 The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed.
3 The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed.
4 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.
5 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.
6 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.
7 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.
8 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in the signal data rate. See through for
information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See the section for guidance on

2 The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed.
3 The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed.
4 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.
5 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.
6 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.
7 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.
8 Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in the signal data rate. See through for
information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See the section for guidance on
calculating per-channel supply current for a given data rate.

1 The supply current values are for both channels 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 ADuM1200W and ADuM1201W channel configurations.
2 The minimum pulse width is the shortest pulse width at which the specified pulse width distortion is guaranteed.
3 The maximum data rate is the fastest data rate at which the specified pulse width distortion is guaranteed.
4 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.
5 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.
6 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.
7 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.
8 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 as a function of data rate 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
PCB LAYOUT
The ADuM120x 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.
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 low output can differ from the propagation delay
to a logic high output.

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 timing of the input signal is preserved.
Channel-to-channel matching refers to the maximum amount
that the propagation delay differs between channels within a
single ADuM120x component.
Propagation delay skew refers to the maximum amount that
the propagation delay differs between multiple ADuM120x
components operating under the same conditions.
DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY
Positive and negative logic transitions at the isolator input send
narrow (~1 ns) pulses 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 transi-
tions of more than ~1 μs at the input, 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 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 17 and Table 18) by the
watchdog timer circuit.
The ADuM120x are extremely immune to external magnetic
fields. The limitation on the magnetic field immunity of the
ADuM120x 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 can occur. The 3 V
operating condition of the ADuM120x 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)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).
Given the geometry of the receiving coil in the ADuM120x 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 13.

Data Sheet ADuM1200/ADuM1201
Rev. I | Page 25 of 28
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 away from the
ADuM120x transformers. Figure 14 expresses these allowable
current magnitudes as a function of frequency for selected
distances. As seen, the ADuM120x are extremely immune and
can be affected only by extremely large currents operating very
close to the component at a high frequency. For the 1 MHz
example, a 0.5 kA current would have to be placed 5 mm away
from the ADuM120x to affect the operation of the component.

Note that, at combinations of strong magnetic fields and high
frequencies, any loops formed by PCB traces can induce suffi-
ciently large error voltages to trigger the threshold of succeeding
circuitry. Care should be taken in the layout of such traces to
avoid this possibility.
POWER CONSUMPTION
The supply current at a given channel of the ADuM120x
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
For each output channel, the supply current is given by
IDDO = IDDO (Q) f ≤ 0.5fr
IDDO = (IDDO (D) + (0.5 × 10−3) × 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 supply currents, the supply
currents for each input and output channel corresponding to
IDD1 and IDD2 are calculated and totaled. Figure 6 and Figure 7
provide per-channel 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
VDD1 and VDD2 supply current as a function of data rate for
ADuM1200 and ADuM1201 channel configurations.

In the case of unipolar ac or dc voltage, the stress on the insu-
lation is significantly lower, which allows operation at higher
working voltages yet still achieves a 50-year service life. The
working voltages listed in Table 14 can be applied while main-
taining 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 16
or Figure 17 is to be treated as a bipolar ac waveform, and its
peak voltage is to be limited to the 50-year lifetime voltage value
listed in Table 14.
INSULATION LIFETIME
All insulation structures eventually break down when subjected
to voltage stress over a sufficiently long period. The rate of insu-
lation 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 ADuM120x.
Analog Devices performs accelerated life testing using voltage
levels higher than the rated continuous working voltage. Accel-
eration 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 volt-
ages. 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 sinu-
soidal 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 ADuM120x 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, respectively.
