ADUM241D1BRWZ

Overview

The ADUM241D1BRWZ is a robust quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 3:1 channel configuration with three forward and one reverse unidirectional path. The device supports data rates up to 150 Mb/s and offers an isolation voltage of 5000 Vrms. It operates within a temperature range of -40°C to +125°C and is housed in a 16-lead SOIC package. Key electrical parameters include a propagation delay of 7.2 ns and a common-mode transient immunity of 75 kV/µs.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for high-speed signal transmission without external magnetics.
• Provides robust isolation with high common-mode transient immunity suitable for noisy environments.
• Features a flexible 3:1 channel architecture supporting various bidirectional or unidirectional logic configurations.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors.
• Medical equipment interfaces needing certified isolation barriers for patient safety.
• Power electronics control circuits isolating gate drivers from low-voltage logic.

Procurement Notes

Verify the specific suffix 'D1' indicates the correct channel directionality and pinout for your design. Confirm RoHS compliance status and moisture sensitivity level requirements before ordering. Check for any recent product change notices that may affect packaging or specifications. Ensure the 16-SOIC footprint matches your PCB layout constraints.

Selection Notes

Select this component when high-speed data transfer above 10 Mbps is required alongside strong noise immunity. The 75 kV/µs CMTI rating makes it superior to older capacitive isolators in high-dv/dt environments. Consider the 3:1 channel split if only one return path is needed. Verify supply voltage compatibility with the 1.7V to 5.5V operating range.

Part Context

This part belongs to the ADuM241 family of robust digital isolators. It shares the same core iCoupler technology as the ADUM241E series but differs in specific performance grades and qualification levels. The 'D1' designation specifies the internal channel mapping and directionality distinct from other variants like the D0 or E1 models.

Replacement Considerations

The ADUM241E1BRIZ is a parameter-equivalent alternative within the same family. The ADUM241D1BRIZ is another compatible variant offering similar functionality in a tube package. Verify pin-to-pin compatibility and specific electrical limits before substituting.
