The ADUM1100ARADUM1100AR is a digital isolator based on Analog Devices Inc. iCoupler technology. Combining high speed CMOS and monolithic air core 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 ADUM1100ARADUM1100AR supports data rates as high as 25 Mbps and 100 Mbps.

The ADUM1100ARADUM1100AR operates with a voltage supply ranging from 3.0 V to 5.5 V, boasts a propagation delay of <18 ns and edge asymmetry of <2 ns, and is compatible with temperatures up to 125°C. It operates at very low power, less than 0.9 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 ADUM1100ARADUM1100AR provides dc correctness with a patented refresh feature that continuously updates the output signal.

The ADUM1100ARADUM1100AR is offered in three grades. The ADUM1100ARADUM1100AR and ADuM1100BR can operate up to a maximum temperature of 105°C and support data rates up to 25 Mbps and 100 Mbps, respectively. The ADuM1100UR can operate up to a maximum temperature of 125°C and supports data rates up to 100 Mbps.
