Description

Feature

The ADUM1250 series, a technological advance in digital isolators designed to improve data reliability in I2C interfaces, is introduced by Analog Devices Inc. By providing smooth bidirectional channels and doing away with the need for signal splitting across different optocouplers, these isolators go above and beyond traditional communication facilitation.
This product's two integrated bidirectional channels provide complete isolation for computer interfaces. Devices can be added or removed from an active bus without interfering with data flow thanks to its ingenious hot-swapping control.
Leveraging Analog Devices' iCoupler® chip-scale transformer technology, these isolators excel not only in size but also in performance and power efficiency compared to traditional optocouplers. By merging iCoupler channels with semiconductor circuits, they deliver a compact yet fully isolated I²C interface solution, ensuring enhanced reliability in various applications. Additionally, certified for safety standards such as UL 1577 and boasting a 25kV/µs Common Mode Transient Immunity, these isolators guarantee steadfast performance even in demanding environments.
