ADuM3100 Series

Digital Isolator, Enhanced System-Level ESD Reliability

Analog Devices Inc.

The ADuM31001 is a digital isolator based on the Analog Devices, Inc. iCoupler® technology.

Product 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 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 160µA 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.
