Triple-Channel, Digital Isolators,
Enhanced System-Level ESD Reliability
Data Sheet
ADuM3300/ADuM3301
FEATURES
GENERAL DESCRIPTION
The ADuM3300/ADuM33011 are 3-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 superior to alternatives, such as optocoupler devices.
Enhanced system-level ESD performance per IEC 61000-4-x
Low power operation
5 V operation
2.0 mA per channel maximum at 0 Mbps to 2 Mbps
4.1 mA per channel maximum at 10 Mbps
36 mA per channel maximum at 90 Mbps
3.3 V operation
1.0 mA per channel maximum at 0 Mbps to 2 Mbps
2.8 mA per channel maximum at 10 Mbps
17 mA per channel maximum at 90 Mbps
Bidirectional communication
iCoupler devices remove the design difficulties commonly
associated with optocouplers. 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. The need for external drivers and other discrete
components is eliminated with these iCoupler products.
Furthermore, iCoupler devices consume one-tenth to one-sixth
the power of optocouplers at comparable signal data rates.
3.3 V/5 V level translation
High temperature operation: 105°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, RoHS-compliant package
Safety and regulatory approvals
UL recognition: 2500 V rms for 1 minute per UL 1577
CSA Component Acceptance Notice 5A
VDE Certificate of Conformity
DIN V VDE V 0884-10 (VDE V 0884-10): 2006-12
VIORM = 560 V peak
The ADuM3300/ADuM3301 isolators provide three 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 3.3 V to 5.5 V, providing
compatibility with lower voltage systems as well as enabling a
voltage translation functionality across the isolation barrier. The
ADuM3300/ADuM3301 isolators have a patented refresh feature
that ensures dc correctness in the absence of input logic
transitions and during power-up/power-down conditions.
In comparison to ADuM1300/ADuM1301 isolators, ADuM3300/
ADuM3301 isolators contain various circuit and layout changes
to provide increased capability relative to system-level IEC
61000-4-x testing (ESD, burst, and surge). The precise capability
in these tests for either the ADuM1300/ADuM1301 or
ADuM3300/ADuM3301 products is strongly determined by the
design and layout of the user’s system.
CQC Certification per GB4943.1-2011

General-purpose multichannel isolation
