The ADuM1280/ADuM1281/ADuM1285/ADuM1286 1 (also
referred to as ADuM128x in this data sheet) are dual-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 and other integrated
couplers.
APPLICATIONS
General-purpose multichannel isolation
Data converter isolation
Industrial field bus isolation
With propagation delay at 20 ns, pulse width distortion is less
than 2 ns for C grade. Channel-to-channel matching is tight at
5 ns for C grade. The two channels of the ADuM128x are
independent isolation channels and are available in two channel
configurations with three different data rates up to 100 Mbps
(see the Ordering Guide). All models 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.
Unlike other optocoupler alternatives, the ADuM128x isolators
have a patented refresh feature that ensures dc correctness in
the absence of input logic transitions. When power is first
applied or is not yet applied to the input side, the ADuM1280
and ADuM1281 have a default high output, and the ADuM1285
and ADuM1286 have a default low output.

APPLICATIONS INFORMATION
PC BOARD LAYOUT
The ADuM128x digital isolator requires no external interface
circuitry for the logic interfaces. Power supply bypassing is
strongly recommended at both input and output supply pins
VDD1 and VDD2 (see Figure 12). 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.
The ADuM128x can readily meet CISPR 22 Class A (and
FCC Class A) emissions standards, as well as the more
stringent CISPR 22 Class B (and FCC Class B) standards in
an unshielded environment, with proper PCB design choices.
Refer to the AN-1109 Applicaton Note, Recommendations for
Control of Radiated Emissions with iCoupler Devices for PCBrelated EMI mitigation techniques, including board layout and
stack-up issues.
PROPAGATION DELAY-RELATED PARAMETERS
Propagation delay is a parameter that describes the time it takes
a logic signal to propagate through a component. The input-tooutput propagation delay time for a high-to-low transition may
differ from the propagation delay time of a low-to-high
transition.
50%
If the decoder receives no pulses for more than about 6.4 µs, the
input side is assumed to be unpowered or nonfunctional, in which
case, the isolator output is forced to a default low state by the
watchdog timer circuit.
The limitation on the device’s 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 such conditions. The
ADuM1280 is examined in a 3 V operating condition because it
represents the most susceptible mode of operation of this product.
The pulses at the transformer output have an amplitude greater
than 1.5 V. The decoder has a sensing threshold of about 1.0 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)∑πrn2; n = 1, 2, …, N
tPHL
OUTPUT (VOx)
10444-012
tPLH
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 ~1.6 µs,
a periodic set of refresh pulses indicative of the correct input
state are sent to ensure dc correctness at the output.
50%
Figure 12. Propagation Delay Parameters
Pulse width distortion is the maximum difference between
these two propagation delay values and an indication of how
accurately the timing of the input signal is preserved.
Propagation delay skew refers to the maximum amount the
propagation delay differs between multiple ADuM128x
components operating under the same conditions.
Given the geometry of the receiving coil in the ADuM1280 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 13.

IMMUNITY
ADuM1280/ADuM1281/ADuM1285/ADuM1286
For example, at a magnetic field frequency of 1 MHz, the
maximum allowable magnetic field of 0.08 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.
If such an event occurs, with the worst-case polarity, during a
transmitted pulse, it would reduce the received pulse from >1.0 V
to 0.75 V. This is 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 ADuM1280
transformers. Figure 14 expresses these allowable current magnitudes as a function of frequency for selected distances. The
ADuM1280 is very insensitive to external fields. Only extremely
large, high frequency currents, very close to the component
could potentially be a concern. For the 1 MHz example noted,
one would have to place a 0.2 kA current 5 mm away from the
ADuM1280 to affect component operation.
Data Sheet
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. Take care to avoid PCB
structures that form loops.
POWER CONSUMPTION
The supply current at a given channel of the ADuM128x
isolator is a function of the supply voltage, the data rate of
the channel, and the output load of the channel.

show per-channel supply currents as a function of data rate for
an unloaded output condition. Figure 8 shows the per-channel
supply current as a function of data rate for a 15 pF output
condition. Figure 9 through Figure 11 show the total VDD1 and

INSULATION LIFETIME
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 ADuM128x.
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 19 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.
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 19 can be applied while maintaining the 50-year minimum lifetime provided the voltage
conforms to either the unipolar ac or dc voltage case. Any crossinsulation 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 19.
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 ADuM128x 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.
