ADUM340E0BRQZ-RL7

Overview

The ADUM340E0BRQZ-RL7 is a quad-channel digital isolator from the Analog Devices ADuM340 series, utilizing iCoupler magnetic coupling technology. It features four unidirectional data channels with a maximum data rate of 150 Mb/s and a typical propagation delay of 6.2 ns. The device operates on supply voltages between 2.25 V and 5.5 V, drawing approximately 6.3 mA to 8.5 mA depending on channel configuration. It provides enhanced insulation voltage ratings of 3 kVrms and 5.7 kVrms, ensuring robust signal integrity in high-noise environments.

Feature Summary

• Integrates four independent unidirectional data channels within a single package for compact system design
• Employs iCoupler technology to provide high common-mode transient immunity and noise rejection
• Supports flexible logic levels with wide supply voltage operation ranging from 2.25 V to 5.5 V
• Features guaranteed low pulse width distortion for precise timing applications

Applications

• Isolation for Serial Peripheral Interface (SPI) communication buses
• Signal isolation for RS-485 and Controller Area Network (CAN) networks
• Industrial fieldbus isolation in automation systems
• PWM controller signal isolation in power electronics

Procurement Notes

Verify the specific suffix 'E0' indicates the fault-safe low output configuration distinct from other variants. Confirm the QSOP-16 package availability and moisture sensitivity level requirements during storage and handling. Ensure the ordering part number matches the exact channel count and polarity specifications required for the target circuit design.

Selection Notes

Select this component when four isolated bidirectional or unidirectional paths are required in a space-constrained layout. The E0 variant is appropriate for applications requiring a defined low state upon power loss or fault conditions. Consider the 150 Mb/s speed limit and 5.7 kVrms isolation rating against system voltage and bandwidth demands.

Part Context

This part belongs to the ADuM34x family of quad digital isolators, designed to replace traditional optocouplers in high-speed digital interfaces. The family offers superior performance in terms of propagation delay consistency and power consumption compared to legacy isolation technologies.

Replacement Considerations

Direct substitutes include ADUM340E1BRQZ-RL7 (fault-safe high) and ADUM340E0BRWZ-RL (wide body package). Verify pinout compatibility and insulation clearance requirements when transitioning between standard and wide-body SOIC packages.
