ADUM240E1BRWZ

Overview

The ADUM240E1BRWZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides robust isolation with a rated insulation voltage of 5000 Vrms and a common-mode transient immunity (CMTI) of 75 kV/µs. The device supports data rates up to 150 Mb/s with a maximum propagation delay of 7.2 ns. It operates on a single supply voltage ranging from 1.7 V to 5.5 V and draws an operating supply current of 11.8 mA. Designed for automotive applications, it holds AEC-Q100 qualification and functions within a temperature range of -40°C to +125°C. The component is housed in a 16-lead SOIC package.

Feature Summary

• Integrates four independent unidirectional channels using proprietary iCoupler magnetic coupling technology for signal transmission across isolation barriers.
• Delivers high-speed data integrity with a throughput capability of 150 Mbps and minimal propagation delay for precise timing applications.
• Ensures system safety and noise rejection through a 5000 Vrms insulation rating and superior common-mode transient immunity of 75 kV/µs.
• Supports flexible power integration by operating on a wide single-supply voltage range from 1.7 V to 5.5 V.

Applications

• Automotive electronic control units requiring AEC-Q100 qualified isolation
• Industrial communication interfaces such as CAN and LIN bus systems
• Motor drive circuits needing isolated gate driving signals
• Medical equipment requiring reinforced electrical isolation

Procurement Notes

Verify the specific suffix 'BRWZ' to confirm the SOIC-16 surface-mount package and reel packaging configuration. Ensure the 'E1' designation matches the required 75 kV/µs CMTI specification, as other variants may offer lower transient immunity. Confirm AEC-Q100 automotive qualification status if deploying in vehicle environments. Cross-reference the manufacturer part number against official Analog Devices documentation to avoid confusion with similar ADuM24x series components that may have different channel configurations or speed ratings.

Selection Notes

Select this component when high-speed bidirectional data transfer is not required, as it features unidirectional channels only. It is suitable for designs needing a wide input voltage range compatible with both 1.8 V and 3.3 V logic levels. Consider this part for applications demanding high reliability in electrically noisy environments due to its strong transient immunity. Verify that the thermal performance of the SOIC-16 package meets the junction temperature requirements for the intended operating environment.

Part Context

This device belongs to the ADuM240E family of robust iCoupler digital isolators. It shares architectural similarities with the ADUM240D and ADUM241E series but offers distinct performance characteristics regarding channel directionality and transient immunity. The E-series typically denotes enhanced specifications compared to standard industrial grades, specifically targeting automotive and high-reliability industrial markets.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include ADUM240E1BRIZ and ADUM240E1BRWZ-RL. These alternatives share identical electrical specifications and pinouts but differ in packaging format, such as tube versus reel. Verify that any replacement maintains the same 75 kV/µs CMTI rating and AEC-Q100 qualification status.
