ADUM241E1BRIZ

Overview

The ADUM241E1BRIZ 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 Mbps and offers an isolation voltage of 5000 Vrms. Key electrical parameters include a propagation delay of 7.2 ns, common-mode transient immunity of 75 kV/µs, and a supply current of 11.4 mA. It operates within a temperature range of -40°C to +125°C and is housed in a 16-SOIC package.

Feature Summary

• Utilizes proprietary iCoupler magnetic coupling technology for signal transmission across isolation barriers without optical components.
• Provides high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Features a flexible 3:1 channel architecture allowing independent configuration of forward and reverse data paths.
• Designed for automotive applications with AEC-Q100 qualification and extended industrial temperature range capability.

Applications

• Automotive electronic control units requiring robust galvanic isolation
• Industrial communication interfaces such as CAN and LIN bus systems
• Medical equipment needing high-voltage isolation for patient safety
• Power electronics gate drive circuits with isolated feedback

Procurement Notes

Verify the specific suffix 'E1' against the official datasheet to confirm the exact insulation class and material composition. Ensure the SOIC-16 package width matches your PCB footprint requirements. Confirm AEC-Q100 compliance if the application mandates automotive-grade reliability standards before finalizing procurement.

Selection Notes

Select this component when a 3:1 directional isolation topology is required rather than symmetric bidirectional channels. Compare the 75 kV/µs CMTI specification against system noise levels to ensure adequate margin. Consider the 11.4 mA supply current impact on total power budget relative to lower-power alternatives in the ADuM24x family.

Part Context

This part belongs to the ADuM241E series of robust digital isolators. It shares the same core magnetic coupling architecture as other members but differs in channel count and directionality. The 'E' designation typically indicates enhanced performance or specific automotive qualification compared to standard commercial variants.

Replacement Considerations

ADUM241D1BRWZ is listed as a parameter-equivalent alternative by distributors. Verify that the D-series variant meets all specific insulation and thermal requirements of the original design before substitution.
