Quad-Channel Digital Isolators
Data Sheet
ADuM1400/ADuM1401/ADuM1402
FEATURES
GENERAL DESCRIPTION
Qualified for automotive applications
Low power operation
5 V operation
The ADuM140x1 are quad-channel digital isolators based on
Analog Devices, Inc., iCoupler® technology. Combining high
speed CMOS and monolithic air core transformer technology,
these isolation components provide outstanding performance
characteristics superior to alternatives, such as optocoupler
devices.
1.0 mA per channel maximum @ 0 Mbps to 2 Mbps
3.5 mA per channel maximum @ 10 Mbps
31 mA per channel maximum @ 90 Mbps
3 V operation
0.7 mA per channel maximum @ 0 Mbps to 2 Mbps
2.1 mA per channel maximum @ 10 Mbps
20 mA per channel maximum @ 90 Mbps
Bidirectional communication
By avoiding the use of LEDs and photodiodes, iCoupler devices
remove the design difficulties commonly associated with opto-
couplers. The typical optocoupler concerns regarding uncertain
current transfer ratios, nonlinear transfer functions, and
temperature and lifetime effects are eliminated with the simple
iCoupler digital interfaces and stable performance characteristics.
3 V/5 V level translation
High temperature operation: 125°C
High data rate: dc to 90 Mbps (NRZ)
Precise timing characteristics
2 ns maximum pulse width distortion
2 ns maximum channel-to-channel matching
High common-mode transient immunity: >25 kV/μs
Output enable function
16-lead SOIC wide body package
RoHS-compliant models available
Safety and regulatory approvals
UL recognition: 2500 V rms for 1 minute per UL 1577
CSA Component Acceptance Notice #5A
VDE Certificate of Conformity
The need for external drivers and other discrete components
is eliminated with these iCoupler products. Furthermore,
iCoupler devices consume one-tenth to one-sixth of the power
of optocouplers at comparable signal data rates.
The ADuM140x 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 2.7 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage translation functionality across the isolation barrier. In
addition, the ADuM140x provides low pulse width distortion
(<2 ns for CRW grade) and tight channel-to-channel matching
(<2 ns for CRW grade). Unlike other optocoupler alternatives,
the ADuM140x isolators have a patented refresh feature that
ensures dc correctness in the absence of input logic transitions
and when power is not applied to one of the supplies.
