ADUM240E1BRWZ-RL

Overview

The ADUM240E1BRWZ-RL 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 typical propagation delay of 7.2 ns. It operates within a supply voltage range of 1.7 V to 5.5 V and functions reliably across an extended temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC_W, it features three forward channels and one reverse channel.

Feature Summary

• Integrates four independent CMOS digital isolators using proprietary iCoupler magnetic coupling technology for high-speed signal transmission.
• Delivers high common-mode transient immunity of 75 kV/µs to ensure reliable operation in electrically noisy environments.
• Supports bidirectional communication with a configuration of three forward and one reverse channel within a single package.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral devices.
• Medical equipment interfaces needing certified isolation barriers for patient safety.
• Automotive electronics applications adhering to AEC-Q100 qualification standards.

Procurement Notes

Verify the specific suffix 'E1' against the official Analog Devices datasheet to confirm the exact electrical characteristics and pinout configuration. Ensure the SOIC_W package dimensions match the target PCB footprint. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when high-speed data transfer up to 150 Mbps is required alongside robust noise immunity. The wide supply voltage range allows compatibility with various logic levels. Consider the 16-pin SOIC_W package for surface-mount assembly constraints. Verify that the 5000 Vrms isolation rating satisfies the safety regulations applicable to the specific application domain.

Part Context

This part belongs to the ADuM240 family of quad-channel digital isolators. It shares architectural similarities with other members like the ADUM2401 but offers higher data rates and improved transient immunity. The family utilizes silicon dioxide-based isolation layers integrated with on-chip coils.

Replacement Considerations

The ADUM2401BRWZ is a related variant within the same family but operates at a lower data rate of 10 Mbps. Direct substitution requires verifying if the reduced speed meets system timing requirements. Other ADuM24xx series parts may offer different channel configurations or isolation ratings.
