ADuM2250/ADuM2251 为
Hot-swappable digital isolators，内置非闩锁双向通信通道，且与I
2C接口兼容。这样就不需要将I2C信号分成单独的发送信号与接收信号，供独立光电耦合器使用。
The ADuM2250 provides two bidirectional channels and supports a fully isolated I2C interface. The ADuM2251 offers a bidirectional channel and a unidirectional channel for applications that do not require a bidirectional clock.
Both the ADuM2250 and ADuM2251 have built-in hot-swappable circuitry to prevent data interference when passive cards are inserted into the active bus.
These isolators are based on Analog Devices' iCoupler® chip-scale transformer technology. iCoupler is a magnetic isolation technology that outperforms optocouplers in terms of functionality, performance, size, and power consumption. The ADuM2250/ADuM2251 integrate the iCoupler channel with the semiconductor circuit to enable a fully isolated I2C interface in a small package.
