ADUM163N1BRZ

Digital Isolators Overview

The ADUM163N1BRZ is a six-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides robust isolation with a rated voltage of 3000 Vrms and a common-mode transient immunity of 75 kV/µs. The device supports data rates up to 150 Mbps with typical propagation delays of 7.2 ns. It operates on supply voltages ranging from 1.7 V to 5.5 V and features unidirectional channel configuration. Packaged in a 16-lead SOIC, it functions within an industrial temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Six independent unidirectional channels for general-purpose signal isolation
• High common-mode transient immunity of 75 kV/µs ensures reliable operation in noisy environments
• Magnetic coupling technology eliminates the need for external bootstrap capacitors
• Wide operating supply voltage range supporting both 1.8 V and 5 V logic systems

Digital Isolators Applications

• Isolating SPI communication interfaces in industrial control systems
• Signal isolation between microcontrollers and peripheral devices
• Gate drive isolation for power electronics applications
• Data acquisition systems requiring high-speed digital isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'BRZ' corresponds to the tube packaging variant rather than reel options when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check current availability as distribution may be limited or restricted in certain regions. Ensure the 16-SOIC footprint matches your PCB design constraints before finalizing procurement.

Digital Isolators Selection Notes

Select this component when six isolated channels are required for unidirectional data transmission. The 75 kV/µs CMTI rating makes it suitable for high-noise industrial environments. Consider the 150 Mbps speed limit for application compatibility. The wide supply voltage range allows flexibility in system design. Evaluate thermal performance at maximum operating temperatures to ensure reliability.

Digital Isolators Part Context

This part belongs to the ADuM16xN family of six-channel digital isolators designed specifically for SPI applications. It shares architectural similarities with other members like the ADUM162N and ADUM163N series but differs in channel directionality and pinout configurations. The family emphasizes robust isolation performance using proprietary iCoupler technology without relying on traditional transformer-based methods.

Digital Isolators Replacement Considerations

Public confirmed substitute part numbers: ADUM163N0BRZ (for bidirectional channel variants), ADUM162N1BRZ (similar unidirectional configuration).
