ADUM1250ARZ is a hot-swappable digital isolator incorporating a non-latching bidirectional communication channel compatible with the I²C interface. This eliminates the need to split I²C signals into separate transmit and receive lines for independent optocouplers.

ADUM1250ARZ provides two bidirectional channels supporting a fully isolated I²C interface. The ADUM1251 offers one bidirectional channel and one unidirectional channel, suitable for applications not requiring bidirectional clocking.

ADUM1250ARZ incorporates hot-swap protection circuitry to prevent data corruption when passive cards are inserted into an active bus.

ADUM1250ARZ isolator utilises ADI's iCoupler® chip-scale transformer technology. iCoupler is a magnetic isolation technology that outperforms optocouplers in functionality, performance, size, and power consumption. The ADUM1250ARZ integrates iCoupler channels with semiconductor circuitry to deliver a fully isolated I²C interface within a compact package.
