Working Principles

The ADM101EARMZ-REEL7 utilizes optocoupler technology to achieve signal isolation. The input signal is converted into an optical signal, which is then transmitted across the isolation barrier. On the receiving side, the optical signal is converted back into an electrical signal. This isolation prevents ground loops and protects sensitive circuitry from voltage spikes and noise.

The level shifting functionality is achieved through the use of internal logic circuitry that translates the input logic levels to the desired output logic levels. This allows for seamless communication between systems operating at different voltage levels.
