The ADuM260N/ADuM261N/ADuM262N/ADuM263N1 are
6-channel digital isolators based on Analog Devices, Inc., iCoupler®
technology. Combining high speed, complementary metal-oxide
semiconductor (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. The maximum propagation delay is 13 ns with a pulse width distortion of
less than 4.5 ns at 5 V operation. Channel to channel matching
of propagation delay is tight at 4.0 ns maximum.

GENERAL DESCRIPTION
Figure 3. ADuM262N Functional Block Diagram
VDD1 1
The ADuM260N/ADuM261N/ADuM262N/ADuM263N data
channels are independent and are available in a variety of
configurations with a withstand voltage rating of 5.0 kV rms
(see the Ordering Guide). The devices operate with the supply
voltage on either side ranging from 1.7 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling
voltage translation functionality across the isolation barrier.

Unlike other optocoupler alternatives, dc correctness is ensured
in the absence of input logic transitions. Two different fail-safe
options are available by which the outputs transition to a predetermined state when the input power supply is not applied.

THEORY OF OPERATION
The ADuM260N/ADuM261N/ADuM262N/ADuM263N use
a high frequency carrier to transmit data across the isolation
barrier using iCoupler chip scale transformer coils separated by
layers of polyimide isolation. Using an on/off keying (OOK)
technique and the differential architecture shown in Figure 20
and Figure 21, the ADuM260N/ADuM261N/ADuM262N/
ADuM263N have very low propagation delay and high speed.
Internal regulators and input/output design techniques allow
logic and supply voltages over a wide range from 1.7 V to 5.5 V,
offering voltage translation of 1.8 V, 2.5 V, 3.3 V, and 5 V logic.
The architecture is designed for high common-mode transient
immunity and high immunity to electrical noise and magnetic
interference. Radiated emissions are minimized with a spread
spectrum OOK carrier and other techniques.
Data Sheet
Figure 20 shows the waveforms for models of the
ADuM260N0/ ADuM261N0/ADuM262N0/ADuM263N0 that
have the condition of the fail-safe output state equal to low,
where the carrier waveform is off when the input state is low. If
the input side is off or not operating, the fail-safe output state of
low sets the output to low. For the ADuM260N1/ADuM261N1/
ADuM262N1/ADuM263N1 that have a fail-safe output state of
high, Figure 21 illustrates the conditions where the carrier
waveform is off when the input state is high. When the input
side is off or not operating, the fail-safe output state of high sets
the output to high. See the Ordering Guide for the model
numbers that have the fail-safe output state of low or the fail-safe
output state of high.

APPLICATIONS INFORMATION
PCB LAYOUT
The ADuM260N/ADuM261N/ADuM262N/ADuM263N digital
isolators require no external interface circuitry for the logic
interfaces. Power supply bypassing is strongly recommended at
the input and output supply pins (see Figure 22). Bypass
capacitors are connected between Pin 1 and Pin 8 for VDD1 and
between Pin 9 and Pin 16 for VDD2. The recommended bypass
capacitor value is between 0.01 µF and 0.1 µF. The total lead
length between both ends of the capacitor and the input power
supply pin must not exceed 10 mm.

Model 5104B oscilloscope, 1 GHz, 10 GSPS with the DPOJET

In applications involving high common-mode transients, ensure
that board coupling across the isolation barrier is minimized.
Furthermore, design the board layout such that any coupling
that does occur equally affects all pins on a given component
side. Failure to ensure this can cause voltage differentials between
pins exceeding the Absolute Maximum Ratings of the device,
thereby leading to latch-up or permanent damage.

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 as well as on
the materials and material interfaces.
The two types of insulation degradation of primary interest are
breakdown along surfaces exposed to the air and insulation wear
out. Surface breakdown is the phenomenon of surface tracking,
and the primary determinant of surface creepage requirements
in system level standards. Insulation wear out is the phenomenon
where charge injection or displacement currents inside the
insulation material cause long-term insulation degradation.
Surface Tracking
Surface tracking is addressed in electrical safety standards by
setting a minimum surface creepage based on the working voltage,
the environmental conditions, and the properties of the insulation
material. Safety agencies perform characterization testing on the
surface insulation of components that allows the components to be
categorized in different material groups. Lower material group
ratings are more resistant to surface tracking and, therefore, can
provide adequate lifetime with smaller creepage. The minimum
creepage for a given working voltage and material group is in each
system level standard and is based on the total rms voltage across
the isolation, pollution degree, and material group. The material
group and creepage for the ADuM260N/ADuM261N/
ADuM262N/ADuM263N isolators are presented in Table 9.
Rev. B | Page 21 of 24
ADuM260N/ADuM261N/ADuM262N/ADuM263N
Data Sheet
Testing and modeling have shown that the primary driver of longterm degradation is displacement current in the polyimide
insulation causing incremental damage. The stress on the
insulation can be broken down into broad categories, such as:
dc stress, which causes very little wear out because there is no
displacement current, and an ac component time varying
voltage stress, which causes wear out.
The ratings in certification documents are usually based on
60 Hz sinusoidal stress because this reflects isolation from line
voltages. However, many practical applications have combinations
of 60 Hz ac and dc across the barrier as shown in Equation 1.
Because only the ac portion of the stress causes wear out,
Equation 1 can be rearranged to solve for the ac rms voltage, as
is shown in Equation 2. For insulation wear out with the
polyimide materials used in these products, the ac rms voltage
determines the product lifetime.
VRMS = VAC RMS 2 + VDC 2
VAC RMS = VRMS − VDC
2
VDC
TIME
The working voltage across the barrier from Equation 1 is
VRMS = VAC RMS 2 + VDC 2
VRMS = 2402 + 4002
VRMS = 466 V
This VRMS value is the working voltage used together with the
material group and pollution degree when looking up the
creepage required by a system standard.
To determine if the lifetime is adequate, obtain the time varying
portion of the working voltage. To obtain the ac rms voltage,
use Equation 2.
(1)
VAC RMS = VRMS 2 − VDC 2
VAC RMS = 4662 − 4002
(2)
where:
VAC RMS is the time varying portion of the working voltage.
VRMS is the total rms working voltage.
VDC is the dc offset of the working voltage.

VAC RMS
VAC RMS = 240 V rms
In this case, the ac rms voltage is simply the line voltage of
240 V rms. This calculation is more relevant when the waveform is
not sinusoidal. The value is compared to the limits for working
voltage in Table 15 for the expected lifetime, less than a 60 Hz
sine wave, and it is well within the limit for a 50-year service life.
Calculation and Use of Parameters Example
The following example frequently arises in power conversion
applications. Assume that the line voltage on one side of the
isolation is 240 V ac rms, a 400 V dc bus voltage is present on
the other side of the isolation barrier, and the isolator material
is polyimide. To establish the critical voltages in determining
the creepage, clearance and lifetime of a device, see Figure 25
and the following equations.
Note that the dc working voltage limit in Table 15 is set by the
creepage of the package as specified in IEC 60664-1. This value
can differ for specific system level standards.
Rev. B | Page 22 of 24
14998-025
The lifetime of insulation caused by wear out is determined by
its thickness, material properties, and the voltage stress applied.
It is important to verify that the product lifetime is adequate at
the application working voltage. The working voltage
supported by an isolator for wear out may not be the same as
the working voltage supported for tracking. The working
voltage applicable to tracking is specified in most standards.
