The ADuM3100
1
is a digital isolator based on Analog Devices
i
Coupler technology. Combining high speed CMOS and
monolithic 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 ADuM3100 supports data rates as high
as 25 Mbps and 100 Mbps.
The ADuM3100 operates with a voltage supply ranging from
3.0 V to 5.5 V, boasts a propagation delay of <18 ns and an edge
asymmetry of <2 ns, and is compatible with temperatures up to
105°C. It operates at very low power, less than 2.0 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 ADuM3100 provides dc
correctness with a patented refresh feature that continuously
updates the output signal.
The ADuM3100 is offered in two grades. The ADuM3100AR
and ADuM3100BR can operate up to a maximum temperature
of 105°C and support data rates up to 25 Mbps and 100 Mbps,
respectively.
In comparison to the ADuM1100 digital isolator, the
ADuM3100 contains various circuit and layout changes to
provide increased capability relative to system-level IEC 61000-
4-× testing (ESD/burst/surge). The precise capability in these
tests for either the
ADuM1100
or ADuM3100 is strongly
determined by the design and layout of the user’s board or
module. For more information, see
