ADUM151N1BRZ

Digital Isolators Overview

The ADUM151N1BRZ is a five-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 1.7V to 5.5V and supports data rates up to 150Mbps. The device provides 3000Vrms isolation voltage and withstands 75kV/µs common-mode transient immunity. It features a propagation delay of 7.2ns and operates across an extended temperature range from -40°C to +125°C. Packaged in a 16-lead SOIC, it ensures DC correctness without capacitive coupling.

Digital Isolators Feature Summary

• Utilizes iCoupler magnetic coupling technology for high-speed signal transmission
• Provides robust protection against radiated and conducted noise with high CMTI
• Ensures DC correctness by eliminating capacitive coupling effects
• Supports bidirectional voltage translation between independent power domains

Digital Isolators Applications

• General-purpose multi-channel isolation
• Serial Peripheral Interface (SPI) isolation
• Industrial fieldbus isolation
• Digital-to-analog converter (DAC) isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'BRZ' confirms RoHS compliance and lead-free status. Confirm package dimensions match the 16-SOIC specification. Check humidity sensitivity level requirements for storage and handling. Ensure the operating voltage range aligns with system design constraints.

Digital Isolators Selection Notes

Select this component when five isolated channels are required in a single package. Consider the 150Mbps data rate limit for high-speed applications. Evaluate the 3000Vrms isolation rating against system safety standards. Compare power consumption at the target operating voltage against other isolators.

Digital Isolators Part Context

This part belongs to the ADuM15xN family of five-channel digital isolators. It shares architectural similarities with the ADUM150N and ADUM152N variants. The family is designed for applications requiring multiple isolated signals in compact packages. All variants utilize the same iCoupler technology foundation.

Digital Isolators Replacement Considerations

The ADUM150N1BRZ and ADUM152N1BRZ are direct functional replacements within the same family. Verify channel count and isolation ratings match before substitution. Ensure pin compatibility remains consistent across these specific variants.
