ADUM2402ARIZ

Overview

The ADUM2402ARIZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides four independent channels with unidirectional signal transmission at a data rate of 1 Mb/s. The device operates within a supply voltage range of 2.7 V to 5.5 V and offers an isolation voltage of 5000 Vrms. Key electrical parameters include a propagation delay of 65 ns, rise and fall times of 3 ns, and a common-mode transient immunity of 25 kV/µs. It functions reliably across an industrial temperature range of -40°C to +105°C.

Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology for robust signal transmission.
• Provides high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Supports bidirectional power supply configurations while maintaining unidirectional data flow per channel.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and sensors.
• Medical equipment interfaces needing certified isolation for patient safety compliance.
• Power electronics gate drive circuits where noise immunity is critical.

Procurement Notes

Verify the specific suffix 'ARIZ' to confirm the SOIC-16 package and tube packaging format. Confirm that the unidirectional configuration matches the design requirements, as other variants offer bidirectional capabilities. Check current availability status as distribution may be limited or subject to factory order constraints.

Selection Notes

Select this component when unidirectional communication is sufficient for the application architecture. Compare against higher-speed variants if data rates exceed 1 Mb/s are required. Ensure the 5000 Vrms isolation rating meets the system's safety standards and creepage distance requirements.

Part Context

This part belongs to the ADUM2402 series of quad-channel digital isolators. It shares the same core iCoupler technology family with variants offering different data rates and channel directions. The series is designed to replace traditional optocouplers in applications demanding higher reliability and lower power consumption.
