ADuM2250 Description

The ADuM2250 are hot swappable digital isolators with nontlatching, bidirectional communication channels and are compatible with I2C interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with stand-alone optocouplers.

The ADuM2250 provides two bidirectional channels, supporting a complete isolated I2C interface.

The ADuM2250 contain hot swap circuitry to prevent data glitches when an unpowered card is inserted onto an active bus.

These isolators are based on iCoupler® chip scale transformer technology from Analog Devices, Inc. iCoupler is a magnetic isolation technology with functional, performance, size, and power consumption advantages compared to optocouplers. The ADuM2250 integrate iCoupler channels with semiconductor circuitry to enable a complete, isolated I2C interface provided in a small form factor package.
