ADUM240E0WBRWZ-RL

Overview

The ADUM240E0WBRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mbps and an insulation voltage of 5000 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V and has a typical propagation delay of 65 ns. It supports a common mode transient immunity of 75 kV/µs and functions across an operating temperature range of -40°C to +125°C. Packaged in a 16-lead SOIC.

Feature Summary

• Integrates four independent unidirectional signal paths for robust data transmission.
• Employs iCoupler magnetic coupling technology for high isolation performance.
• Provides high common mode transient immunity to ensure signal integrity in noisy environments.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix and package variant against official Analog Devices documentation to ensure compatibility with design requirements. Confirm availability status through authorized distributors as supply conditions may vary. Ensure compliance with RoHS directives and check for any recent product change notices affecting assembly or sourcing locations before finalizing procurement decisions.

Selection Notes

Select this component when high-speed bidirectional communication is not required, as it offers only unidirectional channels. Consider the 150 Mbps data rate and 75 kV/µs CMTI for applications demanding fast response and noise resilience. Evaluate the 16-lead SOIC package constraints against board space limitations and thermal management needs compared to other isolator families.

Part Context

This part belongs to the ADuM240E series of robust quad-channel digital isolators. It complements other variants like the ADUM2402 by offering higher speed capabilities while maintaining the same physical footprint and isolation principles. The series is designed for general-purpose isolation tasks where channel count and speed are critical factors.

Replacement Considerations

Direct substitutes include other members of the ADuM240 family such as the ADUM2402ARWZ-RL, though differences in data rate and CMTI must be verified. Cross-referencing pinouts and electrical specifications with the latest datasheets is essential to ensure functional equivalence without redesigning the isolation barrier.
