ADUM163N0BRZ

Digital Isolators Overview

The ADUM163N0BRZ is a six-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features a unidirectional configuration with three channels on the input side and three on the output side. The device supports data rates up to 150 Mb/s and provides an insulation voltage of 3000 Vrms. Operating within a supply voltage range of 1.7 V to 5.5 V, it exhibits a typical propagation delay of 7.2 ns and operates across a temperature range of -40°C to +125°C. Packaged in a 16-lead SOIC, it is designed for robust general-purpose isolation applications.

Digital Isolators Feature Summary

• Employs magnetic coupling technology to provide galvanic isolation between circuit sections without optical components.
• Offers a six-channel unidirectional architecture, separating three input channels from three output channels for structured signal routing.
• Delivers high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Supports wide operating voltage ranges, enabling compatibility with various logic families from low-voltage CMOS to 5V systems.

Digital Isolators Applications

• Industrial communication bus isolation
• Medical equipment signal isolation
• Power electronics gate drive circuits

Digital Isolators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level prior to soldering. Ensure storage conditions meet humidity requirements to prevent package damage. Check for specific ordering suffixes that may indicate tape-and-reel packaging versus tube quantities if applicable to your assembly process.

Digital Isolators Selection Notes

Select this component when high channel density and unidirectional signal flow are required in a compact surface-mount package. Consider the 150 Mb/s data rate limit and 3000 Vrms isolation rating against system requirements. Evaluate power consumption at 17 mA against thermal constraints. Compare against other ADuM16xN variants if bidirectional capability or different channel configurations are needed.

Digital Isolators Part Context

This part belongs to the ADuM160N/162N/163N family of six-channel digital isolators designed for SPI and general-purpose applications. These devices integrate multiple isolated channels into a single package to reduce board space compared to discrete solutions. The family shares similar magnetic coupling technology but varies in channel directionality and configuration options to suit diverse interface needs.

Digital Isolators Replacement Considerations

ADUM163N1BRZ offers identical electrical specifications but includes internal pull-up resistors on the output channels. Verify if external pull-ups are present in the design before substituting, as internal resistors may alter signal levels or power consumption characteristics.
