ADUM362N0BRQZ

Digital Isolators Overview

The ADUM362N0BRQZ is a six-channel digital isolator utilizing Analog Devices iCoupler technology, housed in a 16-lead QSOP package. It provides a 3000 Vrms isolation rating with independent power domains ranging from 2.25 V to 5.5 V on both sides. The device supports data rates up to 150 Mb/s at 5 V operation and features a typical propagation delay of 6.2 ns. It includes a fail-safe low output configuration (N0) and operates within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• High common-mode transient immunity of 180 kV/µs for robust noise rejection
• Independent dual-side power supply support enabling voltage translation between logic levels
• Fail-safe low output configuration ensures defined state during input power loss
• Compliance with CISPR 32/EN 55032 Class B limits for electromagnetic interference

Digital Isolators Applications

• Isolation of serial peripheral interface (SPI) data converters
• Isolation of RS-485 communication interfaces
• Controller Area Network (CAN FD) industrial fieldbus isolation
• Pulse width modulation (PWM) controller signal isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'N0' confirms the fail-safe low output characteristic required for your design. Confirm the 'QZ' designation indicates automotive qualification under AEC-Q100 standards if applicable to your environment. Ensure the QSOP-16 package dimensions match your PCB footprint constraints. Check current availability status as distribution may be limited or subject to factory order requirements.

Digital Isolators Selection Notes

Select this component when high-speed SPI or CAN FD isolation is required alongside strict electromagnetic compatibility standards. The 180 kV/µs CMTI rating makes it suitable for noisy industrial environments. The independent power domain feature allows seamless level shifting between different voltage rails without external components. Consider the fail-safe low option if system safety requires a defined low state upon power failure.

Digital Isolators Part Context

This part belongs to the ADuM360N/ADuM362N family of six-channel digital isolators based on iCoupler technology. The family utilizes monolithic air-core transformer coupling for data transmission across the isolation barrier. Variants within the series differ primarily by output configuration options, such as fail-safe high or low states, and packaging types like tube or reel.

Digital Isolators Replacement Considerations

The ADUM362N1WBRQZ-RL7 serves as a functional substitute within the same family, offering identical electrical specifications but featuring a fail-safe high output configuration instead of low. Verify that the change in default output state does not impact system logic requirements before substitution.
