Working Principles

The ISL83088EIUZ utilizes capacitive coupling and proprietary isolation techniques to achieve galvanic isolation between its input and output channels. It employs high-speed digital logic to transmit data across the isolation barrier while maintaining signal integrity.

When a signal is applied to the input channel, it is converted into an isolated signal on the output channel through the isolation barrier. This ensures that any electrical disturbances or voltage differences on one side of the barrier do not affect the other side, providing reliable and secure communication.
