Pin Function Specifications:
The ADUM1201BRZ has 8 pins in total. Here's a detailed breakdown of the pin functions:
Pin No. Pin Name Pin Function 1 VDD1 Power Supply for Side 1: Connect to positive voltage rail (typically +3.3V to +5V). 2 A1 Input Data (Side 1): The data input pin for the first side of the isolator. This is where the data signal from the source is applied. 3 A2 Input Data (Side 1): This is the second data input pin for the first side. 4 GND1 Ground for Side 1: Connect to the ground of the first side. 5 GND2 Ground for Side 2: Connect to the ground of the second side. 6 VDD2 Power Supply for Side 2: Connect to positive voltage rail (typically +3.3V to +5V). 7 B1 Output Data (Side 2): The data output pin for the second side of the isolator. This is where the isolated data is sent from side 2. 8 B2 Output Data (Side 2): This is the second data output pin for the second side of the isolator.Circuit Principle:
The ADUM1201BRZ is based on Analog Devices' iCoupler technology, which uses transformer-based isolation to transfer data between two circuits while maintaining electrical isolation. The key principle is that it isolates high-speed digital signals by converting them into a modulated form and then transferring that form across an isolation barrier, ensuring no direct electrical connection between the two sides.
This ensures that any spikes, noise, or differences in voltage potential between the two circuits do not affect the data integrity or cause damage.
