ADUM2402CRIZ

Overview

The ADUM2402CRIZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7V to 5.5V and supports data rates up to 90Mbps. The device provides 5000Vrms isolation voltage and features a common-mode transient immunity of 25kV/µs. Key electrical parameters include a maximum propagation delay of 32ns, rise/fall times of approximately 2.5ns to 3ns, and a pulse width distortion of 2ns. It functions in bidirectional mode with four channels (1/2/2 split) and operates across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent digital isolation channels using proprietary iCoupler magnetic coupling technology for signal transmission without optical components.
• Provides robust noise immunity with high common-mode transient immunity ratings suitable for electrically noisy industrial environments.
• Supports bidirectional data flow across all channels, allowing flexible configuration for various interface protocols.
• Operates reliably over an extended industrial temperature range while maintaining low power consumption characteristics.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral devices
• Medical equipment interfaces needing high-voltage isolation for patient safety compliance
• Power electronics control circuits isolating gate drivers from logic controllers
• Inverter and motor drive applications demanding reliable signal transmission across potential differences

Procurement Notes

Verify the specific suffix 'CRIZ' corresponds to the SOIC-16 tube packaging variant when ordering. Confirm that the bidirectional channel configuration matches system requirements, as other variants may offer unidirectional options. Ensure compatibility with the required 2.7V to 5.5V supply rails. Check current availability status through authorized distributors, as supply constraints may affect lead times. Validate RoHS compliance documentation if required by regional regulations.

Selection Notes

Select this component when four isolated bidirectional channels are necessary within a single package. Compare against unidirectional variants like the ADUM2401 if directionality can be simplified. Consider the 90Mbps data rate limit against higher-speed alternatives if protocol requirements exceed this threshold. Evaluate the 5000Vrms isolation rating against system safety standards. Assess the SOIC-16 footprint against PCB space constraints compared to wider packages.

Part Context

This part belongs to the ADUM2402 series of quad-channel digital isolators. It shares the core iCoupler architecture with related parts but differs in channel directionality and packaging. The CRIZ designation specifically identifies the commercial grade version in a standard tube format. It complements lower-channel-count isolators and higher-performance variants within the Analog Devices portfolio.

Replacement Considerations

Direct functional substitutes include the ADUM2401CRIZ for unidirectional applications or the ADUM2402BRIZ for alternative speed grades. Verify pinout compatibility before swapping. Ensure replacement parts meet the same isolation voltage and temperature specifications. Cross-reference datasheets for any changes in propagation delay or power consumption metrics.
