• Provides galvanic isolation between circuits using magnetic coupling technology
• Supports bidirectional data transmission across four independent channels
• Operates within a wide supply voltage range of 2.7 V to 5.5 V
• Ensures high common-mode transient immunity for signal integrity

Applications

• Industrial automation control systems requiring isolated communication
• Medical equipment needing patient isolation barriers
• Power electronics monitoring and gate drive applications
• Data acquisition systems with mixed-signal ground separation

Procurement Notes

Verify the specific suffix '53' against official Analog Devices documentation to confirm exact electrical characteristics and pinout compatibility. Confirm RoHS compliance status and check for obsolescence notices, as distributor listings may indicate limited availability or obsolete status for this specific variant.

Selection Notes

Select this component when bidirectional isolation is required for four channels. Ensure the system voltage falls within the 2.7 V to 5.5 V range. Verify that the 1 Mbps data rate meets application timing requirements. Consider the SOIC-16 package dimensions for PCB layout constraints compared to other isolator families.

Part Context

This part belongs to the ADUM1402 series of digital isolators. It utilizes Analog Devices' iCoupler technology for magnetic signal transmission. The series is designed for general-purpose isolation in interface circuits, offering robust performance in harsh electromagnetic environments typical of industrial and automotive applications.

Replacement Considerations

Check for direct replacements like ADUM1402WTRWZ-RL for reel packaging variants. Verify if ADUM1402CRW serves as a compatible tube-packaged alternative. Confirm functional equivalence regarding channel count and isolation voltage before substitution.
