Overview
The ADuM1100BR is a high-speed digital isolator produced by Analog Devices Inc., utilizing the company's proprietary 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 as a pin-compatible replacement for existing high-speed optocouplers and supports data rates up to 100 Mbps. The ADuM1100BR operates with supply voltages ranging from 3.0 V to 5.5 V and is known for its low power consumption and high common-mode transient immunity.
