Pin Functions:
Below is a detailed description of the pin functions for the ADUM1401ARWZ-RL in an 8-pin package:
Pin Number Pin Name Pin Function Description 1 VDD1 Power supply input for side 1 (logic input side). It typically requires 5V or 3.3V (depending on the application). 2 VSS1 Ground for side 1 (logic input side). 3 IN+ Non-inverting input for the digital signal. The input is transferred to the output side through isolation. 4 IN- Inverting input for the digital signal. This works alongside the IN+ pin for differential input. 5 OUT- Inverting output on the output side (logic output side). It receives the signal from the input side and transfers it to the output. 6 OUT+ Non-inverting output on the output side (logic output side). 7 VSS2 Ground for side 2 (logic output side). 8 VDD2 Power supply input for side 2 (logic output side). It is typically 5V or 3.3V depending on the design.Circuit Principle:
The ADUM1401ARWZ-RL works on the principle of capacitive isolation, where digital signals are transmitted through capacitor s, ensuring that there is no direct electrical connection between the input and output sides, which provides isolation and protection to the circuits. The input signal (from side 1) is received through the IN+ and IN- pins. The data is transferred across the isolation barrier to the output side via capacitive coupling, and the output is available at the OUT+ and OUT- pins. The VDD1 and VDD2 pins supply power to each side of the isolator, while VSS1 and VSS2 serve as ground.
