Circuit Principle Instruction:

The ADUM3160 is a digital isolator designed to provide galvanic isolation between two sections of a system. It uses a capacitive coupling technology that isolates the signals while allowing for high-speed data transfer. The isolator typically operates between two voltage domains, allowing the safe transmission of data from one circuit to another without creating a direct electrical path.

Capacitive Coupling Technology: This technology is based on the principle of transmitting signals using capacitor s rather than traditional transformers. It provides high-speed operation and allows for both high voltage isolation and low power consumption. Data Transfer: The ADUM3160 allows data to be transferred between the primary and secondary sides through its inputs and outputs while keeping the grounds isolated. Power Supply: The VDD1 and VDD2 power supply pins provide voltage to the primary and secondary sides of the isolator, respectively. These can be independently powered by different voltage levels, typically either 3.3V or 5V, depending on the application requirements. Ground Isolation: The GND1 and GND2 pins maintain ground isolation between the primary and secondary sides, which is essential for protecting sensitive electronics from ground loops or voltage spikes. Non-Inverting and Inverting Inputs/Outputs: The IN1+, IN1-, OUT1+, and OUT1- pins handle data transmission. IN1+ and IN1- receive the data signal from the primary side, while OUT1+ and OUT1- provide the isolated data signal to the secondary side.
