ADUM340E0WBRQZ

Overview

The ADUM340E0WBRQZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent data channels with a unidirectional configuration (4:0). The device supports a maximum data rate of 150 Mbps and offers an insulation voltage rating of 5.7 kVrms. Operating on a supply voltage range of 2.25 V to 5.5 V, it exhibits a typical propagation delay of 6.2 ns and low dynamic power consumption. The component is housed in a wide-body QSOP-16 package, designed for high reliability in industrial environments.

Feature Summary

• Integrates four independent digital isolation channels using monolithic air-core transformer technology
• Provides enhanced safety ratings with 5.7 kVrms insulation voltage capability
• Supports bidirectional logic level translation between 2.25 V and 5.5 V domains
• Delivers high common-mode transient immunity for robust noise rejection

Applications

• Isolation of SPI communication interfaces
• Signal isolation for RS-485 and CAN bus networks
• Gate drive signal transmission for power electronics
• General-purpose multi-channel digital isolation in industrial systems

Procurement Notes

Verify the specific suffix 'WBRQZ' against the official Analog Devices datasheet to confirm the exact package type and tape-and-reel specifications. Ensure compatibility with your PCB footprint requirements for the wide-body SOIC variant. Confirm that the 5.7 kVrms insulation rating meets your system's safety regulatory standards before finalizing procurement.

Selection Notes

Select this component when four isolated unidirectional channels are required within a single package. It is suitable for applications demanding high data rates up to 150 Mbps and strict channel-to-channel matching. Consider the wide-body package for improved creepage and clearance distances compared to standard SOIC packages.

Part Context

This part belongs to the ADuM34xE family of quad-channel digital isolators. These devices combine CMOS circuitry with iCoupler technology to provide compact, high-performance isolation solutions. The family includes variants with different channel configurations and fault-safe options, all sharing similar electrical characteristics and pinouts.

Replacement Considerations

Direct substitutes include other members of the ADuM34xE series such as ADUM341E or ADUM342E, provided the channel directionality matches the design requirements. Verify that any replacement maintains the same insulation voltage rating and package dimensions.
