ADuM1250/ADuM1251是
Hot-swappable digital isolators，包含与I
2C® 接口兼容的非闩锁、双向通信通道。这样就不需要将I2C信号分成发送信号与接收信号供单独的光电耦合器使用。
The ADuM1250 provides two bidirectional channels and supports a fully isolated I2C interface. The ADuM1251 offers a bidirectional channel and a unidirectional channel for applications that do not require a bidirectional clock.
Both the ADuM1250 and ADuM1251 have built-in hot-swappable circuitry that prevents interference data when a passive card is inserted into the active bus.
These isolators use ADI's iCoupler® chip-scale transformer technology. iCoupler is a magnetic isolation technology that outperforms optocouplers in terms of functionality, performance, size, and power consumption. The ADuM1250/ADuM1251 integrate the iCoupler channel with the semiconductor circuit to achieve a fully isolated 2C interface in a small package.
