Working Principles

The ISL83072EIBZA utilizes capacitive coupling and proprietary digital isolation techniques to transmit data across the isolation barrier. It employs differential signaling to ensure high noise immunity and signal integrity.

When a signal is applied to the input side of the isolator, it is converted into a differential signal and transmitted across the isolation barrier. On the output side, the differential signal is reconstructed into its original form.

The isolation barrier prevents any direct electrical connection between the input and output sides, protecting the circuits from ground loops, voltage spikes, and other potential hazards.
