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 3.15 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 1.
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.

ELECTRICAL CHARACTERISTICS—3.3 V PRIMARY INPUT SUPPLY/3.3 V SECONDARY ISOLATED SUPPLY
All typical specifications are at TA = 25°C, VDD1 = VDD2 = VDDP = 3.3 V, VSEL resistor network: R1 = 10 kΩ, R2 = 16.9 kΩ between VISO and
GNDISO. Minimum/maximum specifications apply over the entire recommended operation range, which is 3.0 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.

1 All voltages are relative to their respective ground.
2 The VISO provides current for dc and dynamic loads on the VISO I/O
channels. 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.
ADuM6210/ADuM6211/ADuM6212
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
