ADUM162N1BRZ

Digital Isolators Overview

The ADUM162N1BRZ is a six-channel digital isolator utilizing Analog Devices iCoupler magnetic coupling technology. It features four unidirectional forward channels and two reverse channels within a 16-lead SOIC package. The device supports data rates up to 150 Mbps with a maximum propagation delay of 13 ns and pulse width distortion under 4.5 ns at 5 V. It operates on supply voltages ranging from 1.7 V to 5.5 V, providing isolation ratings of 3000 Vrms. Key electrical specifications include a common-mode transient immunity of 75 kV/µs and an operating temperature range from -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates high-speed CMOS logic with single-chip air-core transformer technology for robust signal transmission across isolation barriers.
• Provides independent data channels allowing flexible configuration of forward and reverse communication paths.
• Ensures DC correctness without requiring optocoupler feedback loops, eliminating input logic conversion errors.

Digital Isolators Applications

• Industrial automation systems requiring reliable SPI interface isolation
• Medical equipment needing galvanic isolation for safety compliance
• Power electronics control circuits demanding high common-mode noise rejection

Digital Isolators Procurement Notes

Verify the specific suffix 'N1' to confirm the 4-forward/2-reverse channel configuration, as other variants in the ADuM16x family offer different channel arrangements. Ensure the SOIC-16 package matches the target PCB footprint. Confirm RoHS compliance status and moisture sensitivity level requirements before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when a six-channel solution with asymmetric channel distribution is required. It is suitable for applications needing voltage translation between 1.7 V and 5.5 V domains. Consider the 13 ns propagation delay and 75 kV/µs CMTI for high-speed industrial environments where optical isolators may introduce latency or degradation.

Digital Isolators Part Context

This part belongs to the ADuM160N through ADuM163N family of six-channel digital isolators designed specifically for SPI applications. These devices replace traditional optocouplers by integrating magnetic coupling technology directly onto a single silicon chip, offering superior performance in speed, size, and power consumption while maintaining high isolation reliability.

Digital Isolators Replacement Considerations

The ADUM162N0BRZ serves as a functional substitute with identical electrical characteristics but offers a symmetric 3-forward/3-reverse channel configuration instead of the 4/2 split found in the N1 variant.
