I2C Isolator Click

Description of product

I2C Isolator click carries ISO1540, a low-power, bidirectional isolator compatible with I2C interfaces. On the board, the Texas Instruments chip is connected to two sets of I2C pins, one on the mikroBUS connector (SDA, SCL), the other on the upper edge of the board (SCL2, SDL2). ISO1540 uses a silicon dioxide barrier that separates the logic input and output buffers. Bidirectional isolators based on TI’s Capacitive Isolation technology have many advantages over opto-couplers (performance, size, power consumption etc.). When used together with isolated power supplies, they block high voltages, isolate grounds, and prevent interference from from noise currents.
