ADUM340E0BRWZ

Overview

The ADUM340E0BRWZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler technology with integrated CMOS and monolithic air-core transformer capabilities. It features a 5.7 kVrms isolation rating and supports data rates up to 150 Mbps at 5 V operation. The device offers a maximum propagation delay of 10 ns and pulse width distortion under 3 ns, with channel matching within 3.0 ns. Operating voltages range from 2.25 V to 5.5 V on both sides, enabling level shifting. It includes high common-mode transient immunity of 180 kV/μs and meets CISPR 32/EN 55032 Class B limits.

Feature Summary

• Integrates four independent bidirectional data channels with 5.7 kVrms insulation strength
• Provides high common-mode transient immunity for robust noise rejection
• Supports voltage translation between 2.25 V and 5.5 V domains
• Ensures tight channel-to-channel matching for precise timing applications

Applications

• Isolation for Serial Peripheral Interface (SPI) communication
• Data converter isolation in industrial systems
• RS-485 and Controller Area Network (CAN FD) interface isolation
• PWM controller signal isolation
• General-purpose multi-channel isolation requirements

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct channel directionality and fault-safe output states. Confirm that the package variant matches the required PCB footprint. Check for recent regulatory certification updates such as UL or VDE status before finalizing procurement specifications.

Selection Notes

Select this component when high-speed data transmission requires strict channel matching and significant isolation voltage. Consider the 150 Mbps data rate capability and low dynamic power consumption for energy-efficient designs. Ensure the operating temperature range aligns with the application environment, particularly for automotive or industrial settings requiring extended thermal performance.

Part Context

This part belongs to the ADuM34xE series of quad digital isolators designed for high-performance isolation needs. The series leverages iCoupler technology to replace traditional magnetic transformers, offering smaller form factors and better reliability. It is suitable for applications demanding high bandwidth and robust noise immunity in compact packages.

Replacement Considerations

Direct substitutes include other variants within the ADuM34xE family, such as ADUM340E1BRWZ or ADUM340E2BRWZ, depending on required channel directionality. Verify pin compatibility and electrical parameters before substitution.
