ADUM340E1WBRWZ-RL

Overview

The ADUM340E1WBRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent data channels with bidirectional signal transmission in a 16-pin SOIC package. The device supports a supply voltage range of 2.25V to 5.5V and offers an insulation rating of 5700 Vrms. It guarantees a maximum data rate of 150Mbps at 5V operation, with a typical propagation delay of 6.2ns and pulse width distortion under 3ns. The component is qualified to AEC-Q101 standards for automotive applications and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates four independent bidirectional data channels using monolithic air-core transformer technology for robust magnetic isolation.
• Provides high common-mode transient immunity of 180kV/µs (typical) to suppress radiated and conducted noise effectively.
• Supports flexible voltage level translation between 2.25V and 5.5V domains on both sides of the isolation barrier.

Applications

• Isolation for Controller Area Network (CAN) and CAN FD interfaces
• Serial Peripheral Interface (SPI) communication isolation
• RS-485 bus interface isolation
• Industrial fieldbus system isolation

Procurement Notes

Verify the specific suffix 'E1' indicates the fault-safe low output configuration when input power is removed, distinguishing it from other variants like E0 or standard models. Confirm the 'WBRWZ' designation corresponds to the tape-and-reel packaging format required for automated assembly processes. Ensure the component meets the AEC-Q101 qualification requirements if intended for automotive-grade deployments.

Selection Notes

Select this model for applications requiring high-speed data rates up to 150Mbps with strict channel matching constraints. The 5700 Vrms insulation rating suits high-voltage industrial environments. Consider the fault-safe low feature if a defined low state is necessary during power loss scenarios. The wide operating temperature range supports demanding thermal conditions.

Part Context

This component belongs to the ADuM34xE series of quad digital isolators. It shares the same 16-pin SOIC footprint and core iCoupler architecture as siblings like ADUM340E and ADUM341E. The primary distinction lies in the internal logic configuration, specifically the fault-safe output behavior, while maintaining identical electrical performance characteristics and isolation ratings.
