GENERAL DESCRIPTION

The ADuM3100¹is a digital isolator based on Analog Devices

iCoupler® technology. Combining high speed CMOS and

monolithic transformer technology, this isolation component

provides outstanding performance characteristics superior to

alternatives, such as optocoupler devices.

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 Application Note AN-793,

ESD/Latch-Up Considerations with iCoupler Isolation

Products.

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.
