ADUM152N1BRZ

Digital Isolators Overview

The ADUM152N1BRZ is a five-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 4/1 channel configuration (four forward, one reverse) 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 3 ns at 5 V. It operates on supply voltages ranging from 1.7 V to 5.5 V per side, providing 3000 Vrms isolation voltage and 75 kV/µs common-mode transient immunity. Operating temperatures range from -40°C to +125°C.

Digital Isolators Feature Summary

• Provides robust signal isolation via proprietary iCoupler magnetic coupling technology without requiring external transformer drivers.
• Supports independent channel configurations for versatile interface isolation across different logic levels.
• Ensures DC correctness through integrated capacitive isolation barriers that prevent input logic conversion errors.

Digital Isolators Applications

• Serial Peripheral Interface (SPI) and analog-to-digital converter (ADC) isolation
• Industrial fieldbus communication systems
• General-purpose multi-channel signal isolation

Digital Isolators Procurement Notes

Verify the specific suffix '1' indicates the 4/1 channel configuration distinct from other variants like '0'. Confirm RoHS compliance status and moisture sensitivity level requirements during storage. Check current availability as distribution may be limited or subject to factory order constraints.

Digital Isolators Selection Notes

Select this component when four unidirectional channels are required in one direction and one in the opposite direction. Ensure the 1.7 V to 5.5 V dual-supply capability matches the system's voltage translation needs. Verify that the 150 Mbps speed and 3000 Vrms isolation meet the application's electrical safety and bandwidth specifications.

Digital Isolators Part Context

This part belongs to the ADuM15xN family of five-channel digital isolators designed for high-speed, high-reliability applications. It shares core architectural similarities with the ADUM150N and ADUM151N but differs in channel polarity configuration. The series is optimized for SPI and general digital isolation in industrial environments.

Digital Isolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate ADUM150N or ADUM151N only if channel polarity requirements can be adjusted to match their respective configurations.
