隔离式I2C隔离器

ADI公司的隔离式I2C隔离器系列支持完全隔离式I2C接口。该产品系列基于我们的iCoupler®芯片级变压器技术。iCoupler磁隔离技术在功能、性能、尺寸和功耗方面均优于光耦合器。我们采用iCoupler通道与半导体电路集成技术,实现小尺寸完全隔离式I2C接口。我们的I2C隔离器适用于中央交换、联网和以太网供电等应用。
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.
