Overview
The ADuM1100AR-RL7, produced by Analog Devices Inc., is a high-speed digital isolator based on the iCoupler® technology. This component combines high-speed CMOS and monolithic air core transformer technology to provide superior performance characteristics compared to traditional optocoupler devices. It is designed to be a pin-compatible replacement for existing high-speed optocouplers and supports data rates up to 25 Mbps. The ADuM1100AR-RL7 operates with a voltage supply ranging from 3.0 V to 5.5 V and is known for its low power consumption and high common-mode transient immunity.
