ADUM6411BRSZ

Overview

The ADUM6411BRSZ is a quad-channel digital isolator from Analog Devices, featuring an integrated DC-to-DC converter. It provides 3750 Vrms reinforced isolation with four data channels and one reverse channel. The device supports data rates up to 150 Mb/s and offers a maximum propagation delay of 10 ns. It operates within a supply voltage range of 1.7 V to 5.5 V and functions across a temperature range of -40°C to +105°C. Packaged in a 24-pin SSOP.

Feature Summary

• Integrates a high-efficiency DC-to-DC converter for isolated power generation
• Provides robust galvanic isolation using proprietary magnetic coupling technology
• Features a single reverse channel for bidirectional communication support

Applications

• Industrial automation systems requiring isolated communication
• Medical equipment needing reinforced safety isolation
• Power electronics control circuits with high common-mode transient immunity

Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with design requirements. Confirm humidity sensitivity handling procedures are followed during assembly. Check for any recent product change notices regarding pinout or electrical specifications before finalizing procurement.

Selection Notes

Select this component when a compact solution combining four isolated data channels with an integrated power supply is required. It is suitable for designs needing high common-mode transient immunity and low propagation delay. Ensure the input/output voltage levels match the system requirements within the specified operating range.

Part Context

This part belongs to the ADuM64xx series of quad-channel digital isolators. These devices utilize Analog Devices' iCoupler technology to provide signal and power isolation in a small footprint. The series is designed for applications demanding high reliability and performance in noisy environments.

Replacement Considerations

Direct replacements include other ADuM64xx variants with similar channel counts and isolation ratings. Verify that substitute parts maintain the same pinout configuration and integrated converter capabilities to ensure board-level compatibility without redesign.
