Overview
The ADUM1100BR-RL7 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-RL7 operates with a voltage supply ranging from 3.0 V to 5.5 V and is compatible with temperatures up to 100°C. It features low power consumption, with a quiescent current of less than 0.9 mA and a dynamic current of less than 160 μA per Mbps of data rate.
