ADUM163N1BRZ-RL7

Digital Isolators Overview

The ADUM163N1BRZ-RL7 is a six-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a unidirectional 3/3 channel configuration within a 16-SOIC package. The device supports data rates up to 150 Mb/s with a typical propagation delay of 7.2 ns and a maximum of 13 ns. It offers an isolation voltage of 3000 Vrms and a common-mode transient immunity of 75 kV/µs. Operating on a supply voltage range of 1.7 V to 5.5 V, it draws approximately 17 mA per side. The component functions across a temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates high-speed CMOS circuitry with single-chip air-core transformer technology for robust signal transmission.
• Provides independent data channels capable of crossing isolation barriers while performing voltage translation between different logic levels.
• Ensures DC correctness without input logic conversion issues, eliminating the need for optocoupler biasing.

Digital Isolators Applications

• General-purpose isolated SPI communication interfaces
• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal processing circuits

Digital Isolators Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm that the 163N1 variant matches the required 3/3 channel configuration against system schematics. Check RoHS compliance status and moisture sensitivity level requirements prior to assembly planning. Ensure the SOIC-16 footprint aligns with the PCB layout constraints.

Digital Isolators Selection Notes

Select this part for applications demanding high common-mode noise immunity and precise timing matching across multiple channels. The unidirectional nature suits simple data flow architectures. Consider the 1.7 V minimum supply for low-power compatibility. Evaluate thermal dissipation in dense layouts due to the 16-SOIC form factor.

Digital Isolators Part Context

This component belongs to the ADuM16xN family of six-channel digital isolators designed specifically for SPI applications. It replaces traditional optocouplers by offering smaller size, lower power consumption, and better parameter consistency. The family shares core iCoupler technology but varies in channel count and configuration options.

Digital Isolators Replacement Considerations

The ADUM163N0BRZ-RL7 serves as a parameter-equivalent alternative within the same series. Verify if the specific channel configuration differences between the N0 and N1 suffixes impact the design requirements before substitution.
