ADUM2250ARIZ

The ADuM2250 provides two bidirectional channels that support fully isolated I²C interface. The ADuM2251 provides a bidirectional channel and a unidirectional channel for applications that do not require bidirectional clocking.

The ADuM2250/ADuM2251 both have built-in hot-swap circuitry to prevent data interference when a passive card is inserted into an active bus.

These isolators are used by Analog Devices iCoupler® chip-scale transformer technology.iCoupler is a magnetically isolated technology that outperforms photocouplers in functionality, performance, size, and power consumption. ADuM2250/ADuM2251 will iThe Coupler channel is integrated with semiconductor circuitry to achieve fully isolated I in a small package²C interface.
