ADUM1100ARZ - 

The ADUM1100ARZ is a Digital Isolator based on 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 ADuM1100 supports data rates as high as 25Mbps and 100Mbps. The ADuM1100 operates with a voltage supply ranging from 3.0 to 5.5V, boasts a propagation delay of <18ns and edge asymmetry of <2ns and is compatible with temperatures up to 125°C. It operates at very low power, less than 0.9mA 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 ADuM1100 provides DC correctness with a patented refresh feature that continuously updates the output signal.
