Product Overview

The ADUM1250 series hot swappable dual Digital Isolator with non-latching, 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 ADuM1250 provides two bidirectional channels, supporting a complete isolated I²C interface. It contains hot swap circuitry to prevent glitching data when an unpowered card is inserted onto an active bus. It is based on the iCoupler® chip scale transformer technology from Analog Devices, Inc. iCoupler is a magnetic isolation technology with functional, performance, size and power consumption advantages as compared to optocouplers. With the isolator, iCoupler channels can be integrated with semiconductor circuitry, which enables a complete isolated I²C interface to be implemented in a small form factor.
  • Open-drain interfaces
  • 30mA Current sink capability
  • 1000kHz Operation
