ADuM4400W/ADuM4401W/ADuM4402W
FEATURES
GENERAL DESCRIPTION
The ADuM4400W/ADuM4401W/ADuM4402W1 are 4-
channel digital isolators based on the Analog Devices, Inc.,
iCoupler® technology. Combining high speed CMOS and
monolithic air core transformer technology, these isolation
components provide outstanding performance characteristics
that are superior to the alternatives, such as optocoupler devices
and other integrated couplers.
Enhanced system-level ESD performance per IEC 61000-4-x
Safety and regulatory approvals
UL recognition: 5000 V rms for 1 minute per UL 1577
CSA Component Acceptance Notice #5A
IEC 60950-1: 380 V rms (reinforced)
VDE Certificate of Conformity
DIN V VDE V 0884-10 (VDE V 0884-10):2006-12
VIORM = 849 V peak
The ADuM4400W/ADuM4401W/ADuM4402W isolators
provide four independent isolation channels in a variety of
channel configurations and data rates (see the Ordering Guide).
All models operate with the supply voltage on either side
ranging from 3.135 V to 5.5 V, providing compatibility with
lower voltage systems as well as enabling a voltage translation
functionality across the isolation barrier. The ADuM4400W/
ADuM4401W/ADuM4402W isolators have a patented refresh
feature that ensures dc correctness in the absence of input logic
transitions and during power-up/power-down conditions.
Low power operation

4.3 mA per channel maximum @ 10 Mbps
3.3 V operation
0.9 mA per channel maximum @ 0 Mbps to 1 Mbps
2.4 mA per channel maximum @ 10 Mbps
Bidirectional communication
3.3 V/5 V level translation
High temperature operation: 125°C
High data rate: dc to 10 Mbps (NRZ)
Precise timing characteristics
3.5 ns maximum pulse width distortion
3.5 ns maximum channel-to-CHANNEL matching
High common-mode transient immunity: >25 kV/μs
Output enable function
This family of isolators, like many Analog Devices isolators,
offers very low power consumption, consuming one-tenth to
one-sixth the power of comparable isolators at comparable data
rates up to 10 Mbps. All models of the ADuM4400W/
ADuM4401W/ADuM4402W provide low pulse width
distortion (<3.5 ns for WB grade). In addition, every model has
an input glitch filter to protect against extraneous noise
disturbances.
16-lead SOIC wide body package (RW-16)
Qualified for automotive applications
The ADuM4400W/ADuM4401W/ADuM4402W contain circuit
and layout enhancements to help achieve system-level IEC 61000-
4-x compliance (ESD/burst/ surge). The precise capability in these
tests for the ADuM4400W/ADuM4401W/ADuM4402W are
strongly determined by the design and layout of the user’s board or
module. For more information, see the AN-793 Application
Note, ESD/Latch-Up Considerations with iCoupler Isolation
Products.
