GENERAL DESCRIPTION
The ADuM6210/ADuM6211/ADuM62121 are dual-channel
digital isolators with isoPower®, an integrated, isolated dc-to-
dc converter. Based on the Analog Devices, Inc., iCoupler®
technology, the dc-to-dc converter provides regulated, isolated
power that is adjustable between 3.135 V and 5.25 V. Input supply
voltages can range from slightly below the required output to
significantly higher. Popular voltage combinations and their
associated power levels are shown in Table 2.
The ADuM6210/ADuM6211/ADuM6212 eliminate the need
for a separate, isolated dc-to-dc converter in low power, isolated
designs. The iCoupler chip-scale transformer technology is used for
isolated logic signals and for the magnetic components of the dc-
to-dc converter. The result is a small form factor, total isolation
solution.
isoPower uses high frequency switching elements to transfer
power through its transformer. Take special care during printed
circuit board (PCB) layout to meet emissions standards. See the
AN-0971 Application Note for board layout recommendations.

All typical specifications are at TA = 25°C, VDD1 = VDD2 = VDDP = 3.3 V, VSEL resistor network: R1 = 10 k, R2 = 16.9 k between VISO and
GNDISO. Minimum/maximum specifications apply over the entire recommended operation range, which is 3.135 V ≤ VDD1, VDD2, VDDP
3.6 V, and −40°C ≤ TA ≤ +105°C, unless otherwise noted. Switching specifications are tested with CL = 15 pF and CMOS signal levels,
unless otherwise noted.
The digital isolator channels and the power section work independently, and under the operating voltages in this section, there may not
be sufficient current from the VISO to run both data channels at the maximum data rate. Verify that the application is within the power
capability of VISO if that supply is providing power to VDD2.

This current must be included when determining the total VISO supply
current. For ambient temperatures between 85°C and 105°C, maximum
allowed current is reduced.
3 VDDI and VDDO refer to the supply voltages on the input and output sides of a
given channel, respectively. See the PCB Layout section.
4 See Figure 2 for the maximum rated current values for various temperatures.
5 Refers to common-mode transients across the insulation barrier. Common-
mode transients exceeding the absolute maximum ratings may cause latch-up
or permanent damage.
Stresses at or above those listed under Absolute Maximum
Ratings may cause permanent damage to the product. This is a
stress rating only; functional operation of the product at these
or any other conditions above those indicated in the operational
section of this specification is not implied. Operation beyond
the maximum operating conditions for extended periods may
affect product reliability.

APPLICATIONS INFORMATION
The dc-to-dc converter section of the ADuM6210/ADuM6211/
ADuM6212 works on principles that are common to most
modern power supplies. It has a split controller architecture with
isolated pulse-width modulation (PWM) feedback. VDDP power is
supplied to an oscillating circuit that switches current into a chip-
scale air core transformer. Power transferred to the secondary
side is rectified and regulated to a value between 3.135 V and
5.25 V, depending on the setpoint supplied by an external
voltage divider (see Equation 1). The secondary (VISO) side
controller regulates the output by creating a PWM control signal
that is sent to the primary (VDDP) side by a dedicated iCoupler
data channel. The PWM modulates the oscillator circuit to control
the power being sent to the secondary side. Feedback allows for
significantly higher power and efficiency.

R1 is a resistor between VSEL and GNDISO.
R2 is a resistor between VSEL and VISO.
Because the output voltage can be adjusted continuously,
there are an infinite number of operating conditions. This
data sheet addresses three discrete operating conditions in the
Specifications tables. Many other combinations of input and
output voltage are possible; Figure 15 depicts the supported
voltage combinations at room temperature. Figure 15 was
generated by fixing the VISO load and decreasing the input
voltage until the PWM was at 80% duty cycle. Each of the
curves represents the minimum input voltage that is required
for operation under this criterion. For example, if the applica-
tion requires 30 mA of output current at 5 V, the minimum
input voltage at VDDP is 4.25 V. Figure 15 also illustrates why
the VDDP = 3.3 V input and VISO = 5 V configuration is not
recommended. Even at 10 mA of output current, the PWM
cannot maintain less than 80% duty factor, leaving no margin
to support load or temperature variations.
Typically, the ADuM6210/ADuM6211/ADuM6212 dissipates
about 17% more power between room temperature and maxi-
mum temperature; therefore, the 20% PWM margin covers
temperature variations.
The ADuM6210/ADuM6211/ADuM6212 implement
undervoltage lockout (UVLO) with hysteresis on the primary
and secondary side I/O pins as well as the VDDP power input.
This feature ensures that the converter does not go into
oscillation due to noisy input power or slow power-on ramp rates.
PCB LAYOUT
The ADuM6210/ADuM6211/ADuM6212 digital isolators with
0.15 W isoPower integrated dc-to-dc converters require no exter-
nal interface circuitry for the logic interfaces. Power supply
bypassing with a low ESR capacitor is required, as close to the
chip pads as possible. The isoPower inputs require several
passive components to bypass the power effectively as well as
set the output voltage and bypass the core voltage regulator (see
Figure 24 through Figure 26).

Figure 25. VISO Bias and Bypass Components
The power supply section of the ADuM6210/ADuM6211/
ADuM6212 uses a 125 MHz oscillator frequency to efficiently
pass power through its chip-scale transformers. Bypass capaci-
tors are required for several operating frequencies. Noise
suppression requires a low inductance, high frequency
capacitor; ripple suppression and proper regulation require
a large value bulk capacitor. These capacitors are most
conveniently connected between Pin 9 and Pin 10 for VDDP and
between Pin 11 and Pin 12 for VISO. To suppress noise and reduce
ripple, a parallel combination of at least two capacitors is required.
The recommended capacitor values are 0.1 µF and 10 µF for
VDD1. The smaller capacitor must have a low ESR; for example,
use of an NPO or X5R ceramic capacitor is advised. Ceramic
capacitors are also recommended for the 10 F bulk capacitance.
An additional 10 nF capacitor can be added in parallel if further
EMI reduction is required.
Note that the total lead length between the ends of the low ESR
capacitor and the input power supply pin must not exceed 2 mm.

Figure 26. Recommended PCB Layout
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 specified in Table 20,
thereby leading to latch-up and/or permanent damage.

THERMAL ANALYSIS
The ADuM6210/ADuM6211/ADuM6212 consist of four
internal die attached to a split lead frame with two die attach
paddles. For the purposes of thermal analysis, the chip is
treated as a thermal unit, with the highest junction temperature
reflected in the θJA from Table 15. The value of θJA is based
on measurements taken with the devices mounted on a JEDEC
standard, 4-layer board with fine width traces and still air.
Under normal operating conditions, the ADuM6210/
ADuM6211/ADuM6212 can operate at full load across the
full temperature range without derating the output current.
PROPAGATION DELAY PARAMETERS
Propagation delay is a parameter that describes the time it takes
a logic signal to propagate through a component (see Figure 27).
The propagation delay to a logic low output may differ from the
propagation delay to a logic high.

Pulse width distortion is the maximum difference between these
two propagation delay values and is an indication of how
accurately the input signal timing is preserved.
Channel-to-channel matching refers to the maximum amount
the propagation delay differs between channels within a single
ADuM6210/ADuM6211/ADuM6212 component.
Propagation delay skew refers to the maximum amount the
propagation delay differs between multiple ADuM6210/
ADuM6211/ADuM6212 devices operating under the same
conditions.
EMI CONSIDERATIONS
The dc-to-dc converter section of the ADuM6210/ADuM6211/
ADuM6212 components must, of necessity, operate at a very high
frequency to allow efficient power transfer through the small
transformers. This creates high frequency currents that can
propagate in circuit board ground and power planes, causing
edge and dipole radiation. Grounded enclosures are recom-
mended for applications that use these devices. If grounded
enclosures are not possible, follow good RF design practices
in the layout of the PCB. See the AN-0971 Application Note for
the most current PCB layout recommendations for the
ADuM6210/ADuM6211/ADuM6212.
DC CORRECTNESS AND MAGNETIC FIELD IMMUNITY
Positive and negative logic transitions at the isolator input cause
narrow (~1 ns) pulses to be sent 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 transitions at the input for more than 1.6 µs, periodic sets
of refresh pulses that are indicative of the correct input state are
sent to ensure dc correctness at the output. If the decoder receives
no internal pulses of more than approximately 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. This situation should occur in the
ADuM6210/ADuM6211/ADuM6212 only during power-up
and power-down operations.
The limitation on the ADuM6210/ADuM6211/ADuM6212
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
the conditions under which this can occur. The 3.3 V operating
condition of the ADuM6210/ADuM6211/ADuM6212 is
examined because it represents the most susceptible mode of
operation.
The pulses at the transformer output have an amplitude of >1.5 V.
The decoder has a sensing threshold of about 0.5 V, thus estab-
lishing 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
where:
β is the magnetic flux density (gauss).
rn is the radius of the nth turn in the receiving coil (cm).
N is the number of turns in the receiving coil.
Given the geometry of the receiving coil in the ADuM6210/
ADuM6211/ADuM6212 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 28.

Data Sheet ADuM6210/ADuM6211/ADuM6212
Rev. D | Page 21 of 23
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 is of the worst-case polarity), it reduces the received pulse
from >1.0 V to 0.75 V, which 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 from the ADuM6210/
ADuM6211/ADuM6212 transformers. Figure 29 expresses
these allowable current magnitudes as a function of frequency
for selected distances. As shown in Figure 29, the ADuM6210/
ADuM6211/ADuM6212 are extremely immune and can be
affected only by extremely large currents operated at high fre-
quency very close to the component. For the 1 MHz example,
a 0.5 kA current, placed 5 mm away from the ADuM6210/
ADuM6211/ADuM6212, is required to affect component
operation.

Note that, in combinations of strong magnetic field and high
frequency, any loops formed by PCB traces can induce error
voltages that are sufficiently large to trigger the thresholds of
succeeding circuitry. Exercise care in the layout of such traces
to avoid this possibility.
POWER CONSUMPTION
The VDDP power supply input provides power only to the
converter. Power for the data channels is provided through
VDD1 and VDD2. These power supplies can be connected to
VDDP and VISO, if desired; or the supplies can receive power
from an independent source. The converter should be treated
as a standalone supply to be utilized at the discretion of the
designer.
The VDD1 or VDD2 supply current at a given channel of the
ADuM6210/ADuM6211/ADuM6212 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 ≤ 0.5 fr
IDDI = IDDI(D) × (2ffr) + IDDI(Q) f > 0.5 fr
For each output channel, the supply current is given by
IDDO = IDDO(Q) f ≤ 0.5 fr
IDDO = (IDDO(D) + (0.5 × 10−3) × CL × VDDO) × (2f − fr) + IDDO(Q)
f > 0.5 fr
where:
IDDI(D), IDDO(D) are the input and output dynamic supply currents
per channel (mA/Mbps).
IDDI(Q), IDDO(Q) are the specified input and output quiescent
supply currents (mA).
f is the input logic signal frequency (MHz); it is half the input
data rate, expressed in units of Mbps.
fr is the input stage refresh rate (Mbps).
CL is the output load capacitance (pF).
VDDO is the output supply voltage (V).
To calculate the total VDD1 and VDD2 supply current, the supply
currents for each input and output channel corresponding to
VDD1 and VDD2 are calculated and totaled. Figure 18 and
Figure 19 show per-channel supply currents as a function of
data rate for an unloaded output condition. Figure 20 shows the
per-channel supply current as a function of data rate for a 15 pF
output condition. Figure 21 through Figure 23 show the total
VDD1 and VDD2 supply current as a function of data rate for
ADuM6210/ADuM6211/ADuM6212 channel configurations.

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. Analog Devices conducts
an extensive set of evaluations to determine the lifetime of the
insulation structure within the ADuM6210/ADuM6211/
ADuM6212.
Accelerated life testing is performed using voltage levels that are
higher than the rated continuous working voltage. Acceleration
factors for several operating conditions are determined, allowing
calculation of the time to failure at the working voltage of
interest. The values shown in Table 21 summarize the peak
voltages for 50 years of service life in several operating condi-
tions. In many cases, the working voltage approved by agency
testing is higher than the 50-year service life voltage. Operation
at working voltages that are higher than the service life voltage
listed leads to premature insulation failure.
The insulation lifetime of the ADuM6210/ADuM6211/
ADuM6212 depends on the voltage waveform type imposed
across the isolation barrier. The iCoupler insulation structure
degrades at different rates, depending on whether the wave-
form is bipolar ac, unipolar ac, or dc. Figure 30, Figure 31, and
Figure 32 illustrate these different isolation voltage waveforms.
Bipolar ac voltage is the most stringent environment. A 50-year
operating lifetime under the bipolar ac condition determines
the Analog Devices recommended maximum working voltage.
In the case of dc or unipolar ac 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 21 can be applied while
maintaining the 50-year minimum lifetime, provided that the
voltage conforms to either the dc or unipolar ac voltage cases.
Any cross-insulation voltage waveform that does not conform
to Figure 31 or Figure 32 must be treated as a bipolar ac
waveform, and its peak voltage must be limited to the 50-year
lifetime voltage value listed in Table 21.
