ADUM240E1BRIZ

Overview

The ADUM240E1BRIZ is a quad-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a 3:1 input-to-output configuration, housed in a 16-SOIC package. The device supports data rates up to 150 Mbps and offers a minimum common-mode transient immunity of 75 kV/µs. It operates on a supply voltage range of 1.7 V to 5.5 V, with maximum propagation delays of 13 ns for both high-to-low and low-to-high transitions. The isolation rating is 5000 Vrms, and it functions within an extended temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation via proprietary magnetic coupling technology for robust signal transmission.
• Supports high-speed data communication with a maximum rate of 150 Mbps across four independent channels.
• Delivers high common-mode transient immunity of 75 kV/µs to maintain signal integrity in noisy environments.
• Features a wide operating supply voltage range from 1.7 V to 5.5 V for flexible system integration.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing reinforced galvanic isolation
• Power electronics control circuits with high-voltage noise environments
• Test and measurement instrumentation

Procurement Notes

Verify the specific suffix 'E1' against the latest manufacturer datasheet to confirm performance grades and revision status. Ensure the 16-SOIC package dimensions match the target PCB footprint. Confirm RoHS compliance and moisture sensitivity level requirements for the assembly process. Cross-reference the 3:1 channel configuration with system design needs to avoid unused pin issues.

Selection Notes

Select this component when high-speed unidirectional isolation is required with superior transient immunity compared to standard variants. The 150 Mbps data rate suits applications demanding faster throughput than the 10 Mbps or 25 Mbps alternatives. The extended temperature range and 5000 Vrms isolation make it suitable for harsh industrial or medical environments where reliability is critical.

Part Context

This part belongs to the ADuM240 series of quad-channel digital isolators. It shares the same physical package and basic functionality as the ADUM2400 and ADUM2401 but differs in performance specifications such as data rate and CMTI. The 'E1' suffix typically denotes a specific performance grade or revision within the iCoupler family, distinguishing it from lower-speed or different configuration variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct functional equivalents like the ADUM2400 or ADUM2401 series only if their specific electrical parameters meet the application's speed and isolation requirements.
