Overview
The ADUM3200CRZ is a dual-channel digital isolator produced by Analog Devices Inc. It is based on the iCoupler® technology, which combines high-speed CMOS and monolithic transformer technology to provide superior performance compared to traditional optocouplers. This device eliminates the use of LEDs and photodiodes, thereby avoiding issues such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects. The ADUM3200CRZ operates with supply voltages ranging from 3.0 V to 5.5 V and is designed for high-speed data transfer with rates up to 25 Mbps.
