ADUM161N1BRZ

Digital Isolators Overview

The ADUM161N1BRZ is a six-channel digital isolator from the ADUM161N series, manufactured by Analog Devices Inc. It utilizes magnetic coupling technology to provide electrical isolation with a rated insulation voltage of 3000 Vrms. The device features five forward channels and one reverse channel, supporting unidirectional data transmission at speeds up to 150 Mb/s. 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 a maximum power dissipation of 1.64 W. Designed for surface mount installation in a 16-SOIC package, it functions reliably across an extended temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates six independent digital isolation channels using monolithic air-core transformer technology for high-speed signal transmission.
• Provides robust common-mode transient immunity to ensure reliable operation in electrically noisy environments.
• Supports bidirectional logic flow through a configuration of five forward and one reverse channel within a single package.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between control units and sensors
• Medical equipment interfaces needing certified safety isolation for patient-connected circuits
• Power electronics gate drive circuits for isolated switching of power devices

Digital Isolators Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm packaging type and orientation. Confirm that the component meets RoHS compliance requirements for your target market. Check current availability status as distribution may be restricted or limited. Ensure the selected variant matches the required channel configuration and isolation voltage ratings for the intended application design.

Digital Isolators Selection Notes

Select this component when a high-density six-channel solution is required for general-purpose digital isolation. Consider the 16-SOIC footprint for space-constrained printed circuit board layouts. Evaluate the 3000 Vrms isolation rating against system safety standards. Compare the 150 Mb/s data rate capability with interface speed requirements to ensure adequate performance margins.

Digital Isolators Part Context

This part belongs to the ADuM16xN family of six-channel digital isolators designed for SPI applications and general-purpose isolation tasks. The family shares similar magnetic coupling architecture but varies in channel configuration and polarity. The ADUM161N1BRZ specifically offers a 5/1 channel split, distinguishing it from symmetric configurations found in other series members.

Digital Isolators Replacement Considerations

The ADUM161N0BRZ serves as a functional substitute within the same family, offering identical isolation specifications and pinout compatibility while differing only in channel directionality configuration.
