The ADUM1401ARWZ is designed to isolate digital signals between two circuits while maintaining high-speed data transmission. It operates by using micro-transformers inside the device, providing galvanic isolation to prevent voltage spikes or noise from affecting sensitive components on the output side.
It works by having the input side (VDD1, GND1, DIN1, DOUT1) handle the logic signals from the first system, while the output side (VDD2, GND2, DIN2, DOUT2) handles the signals after isolation, ensuring that no direct electrical connection exists between the two sides. This isolation helps in protecting circuits against unwanted interference, voltage transients, and ground loops.
