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.

SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—5 V PRIMARY INPUT SUPPLY/5 V SECONDARY ISOLATED SUPPLY
All typical specifications are at TA = 25°C, VDD1 = VDD2 = VDDP = 5 V, VSEL resistor network: R1 = 10 kΩ, R2 = 30.9 kΩ between VISO and
GNDISO. Minimum/maximum specifications apply over the entire recommended operation range, which is 4.5 V ≤ VDD1, VDD2, VDDP ≤ 5.5 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.
