Dual-Channel Digital Isolators,  
Enhanced System-Level ESD Reliability  
Data Sheet  
ADuM3210/ADuM3211  
FEATURES  
GENERAL DESCRIPTION  
Enhanced system-level ESD performance per IEC 61000-4-x  
High temperature operation: 125°C  
Default low output  
Narrow body, RoHS-compliant, 8-lead SOIC  
Low power operation  
The ADuM3210/ADuM3211 are dual-channel, digital isolators  
based on Analog Devices, Inc., iCoupler® technology. Combining  
high speed CMOS and monolithic transformer technology, this  
isolation component provides outstanding performance charac-  
teristics superior to alternatives such as optocoupler devices.  
5 V operation  
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. 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.  
1.7 mA per channel maximum @ 0 Mbps to 2 Mbps  
3.7 mA per channel maximum @ 10 Mbps  
7.0 mA per channel maximum @ 25 Mbps  
3 V operation  
1.5 mA per channel maximum @ 0 Mbps to 2 Mbps  
2.5 mA per channel maximum @ 10 Mbps  
4.7 mA per channel maximum @ 25 Mbps  
3 V/5 V level translation  
High data rate: dc to 25 Mbps (NRZ)  
Precise timing characteristics  
The ADuM3210/ADuM3211 isolators provide two independent  
isolation channels in two channel configurations with data rates  
up to 25 Mbps (see the Ordering Guide). They operate with 3.3 V  
or 5 V supply voltages on either side, providing compatibility  
with lower voltage systems as well as enabling voltage translation  
functionality across the isolation barrier. The ADuM3210/  
ADuM3211 isolators have a default output low characteristic in  
comparison to the ADuM3200/ ADuM3201 models that have a  
default output high characteristic. ADuM3210W and ADuM3211W  
are automotive grade versions qualified for 125°C operation.  
3 ns maximum pulse-width distortion at 5 V operation  
3 ns maximum channel-to-channel matching  
High common-mode transient immunity: >25 kV/μs  
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

IORM = 560 V peak  
Qualified for automotive applications  
In comparison to the ADuM120x isolator, the ADuM3210/  
ADuM3211 isolators contain various circuit and layout changes  
providing increased capability relative to system-level IEC 61000-4-x  
testing (ESD, burst, and surge). The precise capability in these tests  
for either the ADuM120x or ADuM3210/ADuM3211 products is  
strongly determined by the design and layout of the users board or  
module. For more information, see the AN-793 Application Note,  
ESD/Latch-Up Considerations with iCoupler Isolation Products.  
APPLICATIONS  
Size-critical multichannel isolation  
SPI interface/data converter isolation  
RS-232/RS-422/RS-485 transceiver isolation  
Digital field bus isolation  
Gate drive interfaces  
Hybrid electric vehicles, battery monitor, and motor drive
