GENERAL DESCRIPTION
The ADuM31001 is a digital isolator based on the Analog
Devices, Inc., iCoupler® 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 asym-
metry 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

NOTES
1. FOR PRINCIPLES OF OPERATION, SEE METHOD OF OPERATION,
DC CORRECTNESS, AND MAGNETIC FIELD IMMUNITY SECTION.
Figure 1.
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-x 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 the AN-793 Application Note, ESD/Latch-Up Considerations
with iCoupler Isolation Products.

ELECTRICAL SPECIFICATIONS, 3.3 V OPERATION
All voltages are relative to their respective ground. 3.0 V ≤ VDD1 ≤ 3.6 V, 3.0 V ≤ VDD2 ≤ 3.6 V. All minimum/maximum specifications apply
over the entire recommended operation range, unless otherwise noted. All typical specifications are at TA = 25°C, VDD1 = VDD2 = 3.3 V.
