GENERAL DESCRIPTION  
The ADuM130x1 are triple-channel digital isolators based on the  
Analog Devices, Inc., iCoupler® technology. Combining high  
speed CMOS and monolithic transformer technology, these  
isolation components provide outstanding performance  
characteristics superior to alternatives, such as optocouplers.  
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  
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  
of the power of optocouplers at comparable signal data rates.  
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 ADuM130x isolators provide three independent isolation  
channels in a variety of channel configurations and data rates  
(see the Ordering Guide). Both 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 ADuM130x provide 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 ADuM130x 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.
