ADUM1402CRWZ

Overview

The ADUM1402CRWZ is a quad-channel digital isolator utilizing iCoupler technology. It provides four independent channels with a maximum data rate of 90 Mbps and a common-mode transient immunity (CMTI) of 25 kV/µs. The device operates on a supply voltage range of 2.7 V to 5.5 V, drawing a nominal supply current of 11 mA per channel. It features a propagation delay of 32 ns and an isolation voltage rating of 2500 Vrms. The component is housed in a 16-pin SOIC_W package.

Feature Summary

• Integrates four isolated digital channels within a single compact package
• Employs iCoupler magnetic coupling technology for signal transmission
• Provides high common-mode transient immunity for noise rejection
• Supports unidirectional data flow across all channels

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safety-certified signal isolation
• Power electronics control circuits with high-voltage separation
• Data acquisition systems interfacing analog and digital domains

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape-and-reel versus tube packaging configurations. Ensure compliance with RoHS directives and check for SVHC status as required by regional regulations. Confirm that the ordering part number matches the exact electrical specifications needed for the design.

Selection Notes

Select this component when four isolated channels are required in a space-constrained application. It is suitable for designs needing high CMTI to withstand noisy environments. Consider the 2.7 V to 5.5 V supply range compatibility with existing logic levels. Evaluate the 90 Mbps data rate against system throughput requirements before finalizing the selection.

Part Context

This part belongs to the ADuM1400 series of quad-channel digital isolators from Analog Devices. The series leverages iCoupler technology to replace traditional optocouplers. These devices offer improved performance in terms of speed, power consumption, and reliability while maintaining small form factors suitable for modern PCB layouts.

Replacement Considerations

Check for direct substitutes within the ADuM1400 family, such as ADUM1400 or ADUM1401, which share similar pinouts but may differ in channel count or directionality. Verify that any replacement maintains the required 2500 Vrms isolation rating and 90 Mbps data rate specifications.
