GENERAL DESCRIPTION
The ADuM6410/ADuM6411/ADuM64121 are quad-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. Popular
voltage combinations and the associated power levels are shown
in Table 1.
The ADuM6410/ADuM6411/ADuM6412 eliminate the need for a
separate, isolated dc-to-dc converters 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.
The ADuM6410/ADuM6411/ADuM6412 isolators provide four
independent isolation channels in a variety of channel configura-
tions and data rates (see the Ordering Guide for more
information).

ELECTRICAL CHARACTERISTICS—3.3 V PRIMARY INPUT SUPPLY/3.3 V SECONDARY ISOLATED SUPPLY
All typical specifications are at TA = 25°C, VDD1 = VDDP = VISO = 3.3 V, VSEL resistor network: R1 = 10 kΩ ± 1%, R2 = 16.9 kΩ ± 1% between
VISO and GNDISO (see Figure 31). Minimum/maximum specifications apply over the entire recommended operation range, which is
3.0 V ≤ VDD1, VDDP, VISO ≤ 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.
