ADUM342E0WBRQZ

Overview

The ADUM342E0WBRQZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 2:2 channel configuration with unidirectional data flow. The device supports data rates up to 150 Mbps and operates on supply voltages ranging from 2.25 V to 5.5 V. It provides an insulation voltage of 5.7 kVrms and meets CISPR 32/EN 55032 Class B limits at 5 Mbps. Key electrical parameters include a typical propagation delay of 6.2 ns, maximum pulse width distortion of 0.3 ns, and high common-mode transient immunity of 180 kV/μs.

Feature Summary

• Integrates CMOS and monolithic air-core transformer technology for robust magnetic isolation
• Provides independent data channels with strict channel-to-channel matching
• Supports flexible voltage translation between 2.25 V and 5.5 V domains
• Features fault-safe low output logic configuration

Applications

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

Procurement Notes

Verify the specific suffix WBRQZ against official Analog Devices documentation to confirm package type and tape-and-reel orientation. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Check for any recent product change notices that may affect pinout or electrical characteristics. Ensure design-in compatibility with target system voltage levels and thermal constraints.

Selection Notes

Select this component when a 2:2 isolated interface is required with high-speed data transmission capabilities. The 5.7 kVrms insulation rating suits demanding industrial environments. Consider the 150 Mbps data rate limit and 6.2 ns propagation delay for timing-sensitive designs. The fault-safe low feature ensures predictable states during power loss or initialization phases.

Part Context

This part belongs to the ADuM34xE family of quad digital isolators, which also includes the ADUM340E and ADUM341E variants. These devices share similar core technologies and packaging options but differ in channel configurations and specific application optimizations. The family is designed for general-purpose isolation needs across various industrial and automotive standards.
