ADUM2251ARWZ-RL Description

Short technical summary and product information.

The ADUM2251ARWZ-RL is a digital isolator from Analog Devices Inc. designed for I2C interfaces. It provides nonlatching, bidirectional communication channels, eliminating the need to split I2C signals for separate transmit and receive paths. This device integrates iCoupler® chip-scale transformer technology for magnetic isolation.

Key electrical specifications include a data rate of 1000 kHz, a supply voltage range of 3.0 V to 5.5 V, and a current sink capability of 30 mA. It offers high isolation voltage ratings, including 5000 V rms for 1 minute per UL 1577, 250 V rms (reinforced) per IEC 60601-1, 400 V rms (reinforced) per IEC 60950-1, and a VIORM of 849 V peak per VDE V 0884-10.

The ADUM2251ARWZ-RL is suitable for hot-swap applications, preventing data glitches when unpowered cards are inserted into active buses. It operates at high temperatures up to 105°C. The device is available in a 16-lead SOIC wide body package.

Applications include isolated I2C, SMBus, or PMBus interfaces, multilevel I2C interfaces, power supplies, networking, and Power over Ethernet.
