GENERAL DESCRIPTION
The ADuM1100
Inc., iCoupler® technology. Combining high speed CMOS and
monolithic 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 a 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
alternatives, 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.
