Working Principles

The ISL83072EIUZA utilizes capacitive coupling and proprietary digital isolation technology to transmit data across the isolation barrier. It employs differential signaling techniques to ensure high noise immunity and robustness.

When a signal is applied to one side of the isolator, it is converted into a digital format and transmitted across the isolation barrier using capacitive coupling. On the receiving side, the digital signal is reconstructed and made available for further processing.

The isolation barrier prevents any direct electrical connection between the input and output sides, protecting sensitive components and circuits from potential differences, ground loops, and noise.
