ADUM241E0BRWZ

Overview

The ADUM241E0BRWZ is a robust quad digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 3:1 channel configuration with three forward and one reverse unidirectional channel. The device operates within a supply voltage range of 1.7 V to 5.5 V and supports data rates up to 150 Mb/s. Key electrical parameters include an isolation voltage of 5000 Vrms, a propagation delay of 7.2 ns, and a common-mode transient immunity (CMTI) of 75 kV/µs. It is housed in a 16-lead SOIC package and functions across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates four independent digital isolators using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Provides robust noise immunity with a common-mode transient immunity rating of 75 kV/µs.
• Features a flexible 3:1 channel architecture supporting both unidirectional data flow configurations.
• Operates reliably over an extended industrial temperature range without requiring external components.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripherals.
• Medical equipment interfaces needing high-voltage isolation for patient safety compliance.
• Power electronics control circuits isolating gate drivers from low-side logic.
• Inverter and motor drive applications demanding reliable signal transmission in noisy environments.

Procurement Notes

Verify the specific suffix 'E0' against the official Analog Devices datasheet to confirm the exact insulation and material specifications. Ensure the 16-SOIC footprint matches the target PCB design. Confirm that the 5000 Vrms isolation rating meets the safety requirements of the end application. Check for RoHS compliance status as per the latest manufacturer documentation before finalizing procurement.

Selection Notes

Select this component when a 3:1 channel ratio is required rather than symmetric isolation. Compare the 75 kV/µs CMTI specification against system noise levels to ensure adequate performance. Verify that the 1.7 V minimum supply voltage aligns with the lowest logic level in the circuit. Consider the 16-SOIC package size constraints relative to available board space.

Part Context

This part belongs to the ADuM241E series of robust digital isolators. It shares the same core iCoupler technology and pinout structure as other variants in the family, such as the ADUM241E1 and ADUM241D series. The primary distinction lies in the specific insulation class and regulatory certifications associated with the 'E0' designation within the broader interface IC portfolio.

Replacement Considerations

The ADUM241E1WBRWZ is a parameter-equivalent alternative within the same product family. Verify that the insulation ratings and package dimensions are compatible with the existing design before substitution.
