Overview
The ADUM1200ARZ-RL7 is a dual-channel digital isolator produced by Analog Devices Inc. It utilizes the company's icoupler® technology, which combines high-speed CMOS and monolithic transformer technologies to provide superior performance characteristics compared to traditional optocouplers. This isolator eliminates concerns such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects associated with optocouplers. It is certified by various safety and regulatory standards, including UL recognition 2500V rms for 1 minute per UL 1577, CSA component acceptance notice 5A, VDE certificate of conformity, and DIN V VDE V 0884-10: 2006-12 with a VIORM of 560V peak.
