Pin Function and Specification Details

Here is a detailed explanation of each pin function in a 16-pin SOIC package for the ADUM3201ARZ:

Pin Number Pin Name Function Description 1 VDD2 Power supply for the isolated side (secondary side) of the isolator. It connects to the positive voltage rail of the isolated system (e.g., 5V or 3.3V depending on system). 2 VSS2 Ground reference for the isolated side (secondary side) of the isolator. Connects to the ground of the isolated system. 3 IN1+ Input positive terminal for the first channel of the isolator. The input signal (data or control) for channel 1 is connected to this pin. 4 IN1- Input negative terminal for the first channel of the isolator. Complements the IN1+ signal, ensuring proper differential signal communication. 5 GND2 Ground pin for the isolated side (secondary side). 6 VDD1 Power supply for the primary side of the isolator. It connects to the primary side's power rail, typically 3.3V or 5V. 7 VSS1 Ground pin for the primary side of the isolator. 8 OUT1+ Output positive terminal for the first channel of the isolator. This provides the transmitted data or control signal after isolation. 9 OUT1- Output negative terminal for the first channel. Complements the OUT1+ signal, ensuring proper differential signal reception after isolation. 10 NC No connection (often left floating). 11 VSS1 Ground pin for the primary side (secondary side). 12 VDD1 Power supply pin for the primary side (main power connection). 13 IN2- Input negative terminal for the second channel of the isolator. 14 IN2+ Input positive terminal for the second channel of the isolator. 15 OUT2- Output negative terminal for the second channel after isolation. 16 OUT2+ Output positive terminal for the second channel after isolation.

Principle of Operation
