ADUM1402CRW

Overview

The ADUM1402CRW is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 2500Vrms isolation with a maximum data rate of 90Mbps and a common-mode transient immunity of 25kV/µs. The device operates on a 2.7V to 5.5V supply, features unidirectional channels in a 2/2 configuration, and has a typical propagation delay of 32ns. It is housed in a 16-pin SOIC package.

Feature Summary

• Integrates four independent digital isolation channels within a single compact package.
• Employs iCoupler magnetic coupling technology for signal transmission without optical or transformer components.
• Provides high common-mode transient immunity to reject noise spikes across the isolation barrier.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and sensors.
• Medical equipment interfaces needing certified isolation barriers for patient safety.
• Power electronics monitoring circuits connecting low-voltage controllers to high-voltage power stages.

Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm RoHS compliance and check for moisture sensitivity handling requirements during storage. Ensure the specific suffix matches design specifications as variants exist within the family.

Selection Notes

Select this part for applications requiring four isolated bidirectional or unidirectional channels. Compare against higher-speed variants if data rates exceed 90Mbps. Consider thermal management and PCB layout constraints associated with the SOIC-16 package width.

Part Context

This component belongs to the ADuM140x series of quad-channel isolators from Analog Devices. It shares architectural similarities with the ADUM1400 and ADUM1401 but offers distinct channel directionality options. The series represents a transition from older discrete isolation solutions to integrated magnetic coupling devices.

Replacement Considerations

Public confirmed substitute part numbers include ADUM1402BRWZ and ADUM1402WSRWZ. Verify pinout compatibility and electrical parameter alignment before substitution.
