Overview
The ADUM1401WTRWZ53-RL is a quad-channel digital isolator produced by Analog Devices Inc. This component utilizes Analog Devices' iCoupler technology, which combines high-speed CMOS and monolithic magnetic coupling to achieve reliable and high-speed data transfer across isolation barriers.
The ADUM1401 is designed with a 3/1 channel directionality, meaning three channels are directed from the input side to the output side, and one channel is directed from the output side to the input side. This configuration makes it versatile for various applications requiring digital isolation.
