ADUM341E0BRQZ-RL7

Digital Isolators Overview

The ADUM341E0BRQZ-RL7 is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 3:1 channel configuration with three forward and one reverse channel. Key electrical parameters include a data rate of 150 Mb/s, propagation delay of 6.2 ns, and insulation voltage of 3 kVrms to 5.7 kVrms. Operating on a supply voltage range of 2.25 V to 5.5 V, it draws 6.7 mA or 7.9 mA depending on the side. The device operates within a temperature range of -40°C to +125°C and is housed in a QSOP-16 package.

Digital Isolators Feature Summary

• Integrates four independent digital channels using high-speed CMOS and monolithic transformer technology for robust signal isolation.
• Provides enhanced safety compliance with UL 1577 certification for 5700 VRMS insulation and VDE standards support.
• Features fault-safe logic options (E0/E1 suffixes) ensuring defined output states during power loss or input failure.

Digital Isolators Applications

• Isolation for Serial Peripheral Interface (SPI) communication lines
• Data converter isolation in industrial measurement systems
• RS-485 and Controller Area Network (CAN/CAN FD) bus isolation

Digital Isolators Procurement Notes

Verify the specific suffix 'E0' indicates the fault-safe low output configuration. Confirm the 'QZ' suffix denotes the qualified QSOP-16 package variant. Ensure the '-RL7' designation matches the required reel packaging format for automated assembly processes. Cross-reference the manufacturer part number against official Analog Devices documentation to validate current production status and regional availability constraints.

Digital Isolators Selection Notes

Select this component when a 3:1 unidirectional channel split is required for asymmetric data flow. The 150 Mbps speed supports high-bandwidth applications like CAN FD. The 5.7 kVrms insulation rating suits high-voltage industrial environments. Consider the 6.2 ns propagation delay for timing-sensitive interfaces. Evaluate power consumption requirements against the specified 6.7 mA/7.9 mA operating currents.

Digital Isolators Part Context

This part belongs to the ADuM34xE family of quad digital isolators. It shares the same core iCoupler technology and pinout compatibility with variants like ADUM340E and ADUM342E, differing primarily in channel directionality and fault-safe logic settings. The family is designed for general-purpose multi-channel isolation needs.

Digital Isolators Replacement Considerations

ADUM341E0BRWZ-RL is a compatible alternative offering the same functional specifications in a standard SOIC-16 package instead of QSOP-16. Verify footprint compatibility before substitution.
