2. Pin Function Table:
Below is a detailed pin function description for each of the 8 pins:
Pin Number Pin Name Pin Function Description 1 VDD1 Power supply input for the primary side of the isolator (typically 3.3V or 5V). 2 SDA1 Serial Data (SDA) line for I2C communication on the primary side. 3 SCL1 Serial Clock (SCL) line for I2C communication on the primary side. 4 GND1 Ground for the primary side. 5 GND2 Ground for the secondary side. 6 VDD2 Power supply input for the secondary side of the isolator. 7 SDA2 Serial Data (SDA) line for I2C communication on the secondary side. 8 SCL2 Serial Clock (SCL) line for I2C communication on the secondary side.3. Working Principle:
The ADUM1200 is a digital isolator that provides galvanic isolation between two sides (primary and secondary) using capacitive coupling. It uses a high-speed CMOS (complementary metal-oxide-semiconductor) process to implement the isolation.
Primary Side: The primary side of the device interfaces with a controller (such as a microcontroller), which sends data over the SDA1 and SCL1 lines. Secondary Side: The secondary side interfaces with another system or peripheral using the SDA2 and SCL2 lines. The device isolates the two systems and ensures that there is no direct electrical connection between them, which protects against voltage spikes, electrical noise, and other forms of interference.4.
