Coupler Digital Isolator Data Sheet ADuM1100 FEATURES GENERAL DESCRIPTION High data rate: dc to 100 Mbps (NRZ)
The ADuM11001 is a digital isolator based on Analog Devices
Compatible with 3.3 V and 5.0 V operation/level translation
Inc., iCoupler® technology. Combining high speed CMOS and
125°C maximum operating temperature
monolithic air core transformer technology, this isolation
Low power operation
component provides outstanding performance characteristics
5 V operation
superior to alternatives, such as optocoupler devices.
1.0 mA maximum @ 1 Mbps
Configured as a pin-compatible replacement for existing high
4.5 mA maximum @ 25 Mbps
speed optocouplers, the ADuM1100 supports data rates as high
16.8 mA maximum @ 100 Mbps
as 25 Mbps and 100 Mbps.
3.3 V operation 0.4 mA maximum @ 1 Mbps
The ADuM1100 operates with a voltage supply ranging from
3.5 mA maximum @ 25 Mbps
3.0 V to 5.5 V, boasts a propagation delay of <18 ns and edge
7.1 mA maximum @ 50 Mbps
asymmetry of <2 ns, and is compatible with temperatures up
8-lead SOIC_N package (RoHS compliant version available)
to 125°C. It operates at very low power, less than 0.9 mA of
High common-mode transient immunity: >25 kV/μs
quiescent current (sum of both sides), and a dynamic current
Safety and regulatory approvals
of less than 160 μA per Mbps of data rate. Unlike other optocoupler
UL recognized
alternatives, the ADuM1100 provides dc correctness with a
2500 V rms for 1 minute per UL 1577
patented refresh feature that continuously updates the output

signal.
VDE Certificate of Conformity
The ADuM1100 is offered in three grades. The ADuM1100AR
DIN V VDE V 0884-10 (VDE V 0884-10):2006-12
and ADuM1100BR can operate up to a maximum temperature
VIORM = 560 V peak
of 105°C and support data rates up to 25 Mbps and 100 Mbps,
