5 kV RMS Quad-Channel Digital Isolators  
ADuM4400/ADuM4401/ADuM4402  
FEATURES  
GENERAL DESCRIPTION  
The ADuM440x1 are 4-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 that are superior to the alternatives, such as  
optocoupler devices and other integrated couplers.  
Enhanced system-level ESD performance per IEC 61000-4-x  
Safety and regulatory approvals  
UL recognition 5000 V rms for 1 minute (double protection)  
CSA Component Acceptance Notice #5A (pending)  
IEC 60950-1: 600 V rms (reinforced)  
IEC 60601-1: 250 V rms (reinforced)  
VDE Certificate of Conformity (pending)  
The ADuM440x isolators provide four 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 ADuM440x isolators have a patented refresh feature that  
ensures dc correctness in the absence of input logic transitions  
and during power-up/power-down conditions.

3 V operation  
0.9 mA per channel maximum @ 0 Mbps to 2 Mbps  
2.4 mA per channel maximum @ 10 Mbps  
20 mA per channel maximum @ 90 Mbps  
Bidirectional communication  
This family of isolators, like many Analog Devices isolators,  
offers very low power consumption, consuming one-tenth to  
one-sixth the power of comparable isolators at comparable data  
rates up to 10 Mbps. All models of the ADuM440x provide low  
pulse width distortion (<2 ns for C grade). In addition, every  
model has an input glitch filter to protect against extraneous noise  
disturbances.  
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  
The ADuM440x contain circuit and layout enhancements to help  
achieve system-level IEC 61000-4-x compliance (ESD/burst/surge).  
The precise capability in these tests for the ADuM440x are strongly  
determined by the design and layout of the users board or module.
