Overview
The ADUM2250WARWZ-RL, produced by Analog Devices Inc., is a digital isolator designed for bidirectional I2C communication. This component is part of the ADuM2250/ADuM2251 series, which features hot swappable capabilities and is compatible with I2C, SMBus, and PMBus interfaces. The ADuM2250 provides two bidirectional channels, while the ADuM2251 offers one bidirectional and one unidirectional channel. These isolators utilize iCoupler® chip scale transformer technology, offering advantages in performance, size, power consumption, and functionality compared to traditional optocouplers.
