ADUM163N0BRZ-RL7

Digital Isolators Overview

The ADUM163N0BRZ-RL7 is a six-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 16-pin SOIC package and supports unidirectional data transmission at speeds up to 150 Mb/s. The device provides 3000 Vrms isolation voltage with a common-mode transient immunity of 75 kV/µs. Operating parameters include a supply voltage range of 1.7 V to 5.5 V, maximum propagation delay of 13 ns, and pulse width distortion under 4.5 ns. It functions within a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates high-speed CMOS logic with single-chip air-core transformer technology for robust signal isolation.
• Provides independent data channels allowing flexible configuration across the isolation barrier.
• Ensures DC correctness without input logic conversion issues inherent in optical couplers.
• Supports voltage translation capabilities between different system domains.

Digital Isolators Applications

• Industrial SPI communication interfaces
• General-purpose isolated digital signal transmission
• Multi-channel data acquisition systems

Digital Isolators Procurement Notes

Verify the specific suffix 'RL7' indicates reel packaging when sourcing. Confirm the '0' designation corresponds to the 3/3 channel configuration (three inputs, three outputs). Ensure compatibility with the 16-SOIC footprint during PCB layout. Check current availability status as distribution may be restricted or limited.

Digital Isolators Selection Notes

Select this component for applications requiring high channel density in a small surface-mount package. Consider the 150 Mb/s data rate limit for high-speed bus requirements. Evaluate the 3000 Vrms isolation rating against system safety standards. Compare power consumption characteristics against alternative optocoupler solutions for efficiency.

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 the ADUM160N, ADUM161N, and ADUM162N series, differing primarily in channel configuration and isolation ratings. The family leverages proprietary magnetic coupling to replace traditional optocouplers.
