ADUM2250ARWZ-RL

The ADUM2250ARWZ-RL isolated interface IC is a versatile, high-performance solution suitable for a variety of applications. It supports bidirectional I²C communication, an open-drain interface, and hot-swap capabilities, while also providing 30 mA current sinking capability and high-speed operation up to 1000 kHz. Its wide voltage range, multiple packaging options, high temperature resistance and compliance with strict safety and regulatory standards make it ideal for industrial and automotive applications.

The ADuM2250/ADuM22511 are hot swappable digital isolators with nonlatching, bidirectional communication channels that are compatible with I²C interfaces. This eliminates the need for splitting I²C signals into separate transmit and receive signals for use with standalone optocouplers.

The ADuM2250 provides two bidirectional channels, supporting a complete isolated I²C interface. The ADuM2251 provides one bidirectional channel and one unidirectional channel for those applications where a bidirectional clock is not required.

The ADuM2250/ADuM2251 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 performance, size, power consumption, and functional advantages compared to optocouplers. The ADuM2250/ADuM2251 integrate iCoupler channels with semiconductor circuitry to enable a complete, isolated I²C interface in a small form factor package.
