Circuit Principle Instructions:

The ADUM1200BRZ is based on Analog Devices' iCoupler® technology, which provides high-speed digital isolation. It uses transformer-based isolation to allow signals to pass between two different power domains without direct electrical connection. This helps prevent noise and damage due to high voltage spikes, thus offering protection for sensitive circuits.

Data Input/Output: Pins like DIN1, DIN2 and DOUT1, DOUT2 handle the data transmission from one side of the isolator to the other, while ensuring isolation between the two sides. Power and Ground: Vdd and GND pins for each side are required to provide power to the respective logic and isolated circuits.
