GENERAL DESCRIPTION
The ADuM1100 is a digital isolator based on Analog Devices’
iCoupler technology. Combining high speed CMOS and mono-
lithic air core transformer technology, this isolation component
provides outstanding performance characteristics superior to
alternatives such as optocoupler devices.
Configured as a pin compatible replacement for existing high speed
optocouplers, the ADuM1100 supports data rates as high as
25 Mbps and 100 Mbps.
The ADuM1100 operates with either voltage supply ranging from
3.0 V to 5.5 V, boasts a propagation delay of <18 ns and edge
asymmetry of <2 ns, and is compatible with temperatures up to
125°C. It operates at very low power, less than 0.9 mA of quiescent
current (sum of both sides), and a dynamic current of less than
160 µA per Mbps of data rate. Unlike other optocoupler alter-
natives, the ADuM1100 provides dc correctness with a patented
refresh feature that continuously updates the output signal.
The ADuM1100 is offered in three grades. The ADuM1100AR
and ADuM1100BR can operate up to a maximum temperature
of 105°C and support data rates up to 25 Mbps and 100 Mbps,
respectively. The ADuM1100UR can operate up to a maximum
temperature of 125°C and supports data rates up to 100 Mbps.
