ADUM5411BRSZ-RL7

Overview

The ADUM5411BRSZ-RL7 is a quad-channel digital isolator featuring an integrated isoPower isolated DC-to-DC converter. It provides 2500Vrms isolation voltage and supports data rates up to 150Mbps with a common mode transient immunity of 75kV/µs. The device operates within a temperature range of -40°C to +105°C, drawing 11.4mA operating supply current with a propagation delay of 7.2ns. It utilizes magnetic coupling technology for signal transmission across the isolation barrier.

Feature Summary

• Integrates a high-efficiency isolated DC-to-DC converter to power the secondary side without external components
• Provides robust galvanic isolation using proprietary capacitive coupling technology
• Supports unidirectional data transmission across four independent channels

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing reinforced electrical isolation for safety compliance
• Automotive electronics utilizing CAN or LIN bus networks

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm that the BRSZ designation corresponds to the SSOP package variant. Ensure compatibility with system voltage requirements before procurement. Check current availability status as supply may be restricted. Validate that the component meets all necessary regulatory standards for the intended deployment environment.

Selection Notes

Select this component when a compact solution combining four isolated logic channels with integrated power conversion is required. It is suitable for designs where board space is limited and external isolated power supplies are undesirable. Consider the 2500Vrms isolation rating against system voltage stress levels. Evaluate the 150Mbps data rate capability against application bandwidth needs.

Part Context

This part belongs to the Analog Devices ADuM family of digital isolators. These devices utilize iCoupler technology to provide isolation in a small footprint. The series includes variants with varying channel counts and power configurations. This specific model emphasizes integration by including the isolated power supply on-chip.

Replacement Considerations

Direct substitutes include other ADUM541x series variants with similar channel counts and integrated converters. Verify pinout compatibility and isolation voltage ratings when considering alternatives from other manufacturers.
