Circuit Principle:
The ADUM3201ARZ works on the principle of electrical isolation. It uses transformer-based iCoupler® technology to provide galvanic isolation between its two sides—allowing signals to pass from one side to the other without direct electrical connection. This is crucial in preventing ground loops, protecting sensitive electronics from high voltages, and ensuring signal integrity in noisy environments.
The input signals on the low-voltage side (Di1, Di2) are passed through a high-speed, high-voltage isolation barrier and are output on the high-voltage side (Do1, Do2). The reverse process occurs when signals from the high-voltage side are transmitted back to the low-voltage side.
