I2C Isolators

Analog Devices’ family of isolated I2C isolators support a complete isolated I2C interface. This portfolio is based on our iCoupler® chip scale transformer technology. iCoupler is a magnetic isolation technology with functional, performance, size, and power consumption advantages compared to optocouplers. By integrating iCoupler channels with semiconductor circuitry, our technology enables a complete, isolated I2C interface with a small form factor. Our I2C isolators covers applications such as central office switching, networking, and power over Ethernet.
