Overview
The ADUM2400BRWZ is a quad-channel digital isolator produced by Analog Devices Inc. It is based on Analog Devices' iCoupler® technology, which combines high-speed CMOS and monolithic air core transformer technology. This isolator provides outstanding performance characteristics, superior to traditional optocouplers, by eliminating concerns such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects. The ADUM2400BRWZ operates at significantly lower power than optocouplers, making it an efficient choice for various applications.
