ADuM3100ARZ:  Digital Isolator, Enhanced System-Level ESD Reliability

The ADuM3100* 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 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.
