Triple-Channel, Digital Isolators,
Enhanced System-Level ESD Reliability
ADuM3300/ADuM3301
FEATURES
GENERAL DESCRIPTION
Enhanced system-level ESD performance per IEC 61000-4-x
Low power operation
5 V operation
2.0 mA per channel maximum @ 0 Mbps to 2 Mbps
4.1 mA per channel maximum @ 10 Mbps
The ADuM330x1 are 3-channel digital isolators based on
Analog Devices’ 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.
36 mA per channel maximum @ 90 Mbps
3 V operation
1.0 mA per channel maximum @ 0 Mbps to 2 Mbps
2.8 mA per channel maximum @ 10 Mbps
17 mA per channel maximum @ 90 Mbps
Bidirectional communication
3 V/5 V level translation
High temperature operation: 105°C
High data rate: dc to 90 Mbps (NRZ)
Precise timing characteristics
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.
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, Pb-free 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
The ADuM330x 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 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. The
ADuM330x isolators have a patented refresh feature that ensures dc
correctness in the absence of input logic transitions and during
power-up/power-down conditions.
DIN EN 60747-5-2 (VDE 0884 Part 2): 2003-01
DIN EN 60950 (VDE 0805): 2001-12; EN 60950: 2000
VIORM = 560 V peak
APPLICATIONS
General-purpose multichannel isolation
SPI® interface/data converter isolation
In comparison to the ADuM130x isolators, the ADuM330x
isolators contain various circuit and layout changes to provide
increased capability relative to system-level IEC 61000-4-x
testing (ESD, burst, surge). The precise capability in these tests
for either the ADuM130x or ADuM330x products is strongly
determined by the design and layout of the user’s system.
RS-232/RS-422/RS-485 transceivers
Industrial field bus isolation
