Dual-Channel Digital Isolators,  
Enhanced System-Level ESD Reliability  
ADuM3210/ADuM3211  
GENERAL DESCRIPTION  
FEATURES  
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 ADuM321x1 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 optocouplers. 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 charac-  
teristics. 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.  
1.6 mA per channel maximum @ 0 Mbps to 2 Mbps  
3.7 mA per channel maximum @ 10 Mbps  
3 V operation  
1.4 mA per channel maximum @ 0 Mbps to 2 Mbps  
2.4 mA per channel maximum @ 10 Mbps  
3 V/5 V level translation  
High data rate: dc to 10 Mbps (NRZ)  
Precise timing characteristics  
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  
The two channels of the ADuM321x are independent isolation  
channels and are available in two channel configurations with  
two different data rates up to 10 Mbps (see the Ordering Guide).  
They 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 voltage translation functionality across  
the isolation barrier. The ADuM321x isolators have a default  
output low characteristic in comparison to the ADuM3200/  
ADuM3201 models that have a default output high characteristic.  
The ADuM321x are also available in 125°C temperature grade.  
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  
V
IORM = 560 V peak  
APPLICATIONS  
Size-critical multichannel isolation  
SPI interface/data converter isolation  
RS-232/RS-422/RS-485 transceiver isolation  
Digital field bus isolation  
In comparison to the ADuM120x isolator, the ADuM321x  
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 ADuM321x products is 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.
