ADUM341E0BRWZ-RL

Overview

The ADUM341E0BRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler technology for high-speed signal transmission. It features four unidirectional channels with a maximum data rate of 150 Mb/s and an insulation voltage of 10000 Vrms. The device operates on supply voltages between 2.25 V and 5.5 V, drawing a typical operating current of 10.5 mA. Key electrical parameters include a propagation delay of 6.2 ns, pulse width distortion of 0.3 ns, and a common-mode transient immunity of 100 kV/µs. It is housed in a 16-lead SOIC package and supports an extended operating temperature range from -40°C to +125°C.

Feature Summary

• Provides robust isolation via capacitive coupling technology with high common-mode transient immunity.
• Supports flexible logic levels with independent power supplies on both sides ranging from 2.25 V to 5.5 V.
• Ensures signal integrity through tightly matched channel delays and low pulse width distortion.
• Delivers high-speed performance suitable for demanding industrial communication protocols.

Applications

• Isolation for Controller Area Network (CAN) and CAN FD interfaces
• Signal isolation for RS-485 communication buses
• Serial Peripheral Interface (SPI) isolation in data acquisition systems
• General-purpose multi-channel isolation in industrial automation

Procurement Notes

Verify the specific suffix '0' indicates the fail-safe low output configuration, distinct from other variants like the '1' or '2'. Confirm the '-RL' suffix denotes reel packaging for automated assembly. Ensure the component meets AEC-Q100 automotive qualification requirements if intended for vehicle applications. Check for RoHS compliance status and moisture sensitivity level handling instructions prior to soldering.

Selection Notes

Select this component when high-speed bidirectional or unidirectional isolation is required for digital signals up to 150 Mb/s. The fail-safe low feature ensures a defined state during power loss or fault conditions. Consider the 16-pin SOIC footprint for PCB layout constraints. Evaluate the 10000 Vrms surge rating against system overvoltage requirements. Compare power consumption against alternatives if battery life is critical.

Part Context

This part belongs to the ADuM34xE family of quad digital isolators, designed for applications requiring multiple isolated channels in a compact form factor. The series leverages monolithic transformer technology to achieve high bandwidth and low latency. It serves as a replacement for traditional optocouplers in space-constrained designs needing higher reliability and faster switching speeds.

Replacement Considerations

Direct pin-to-pin replacements within the same family include ADUM341E1BRWZ-RL and ADUM341E2BRWZ-RL, which differ primarily in fail-safe output states. Cross-family comparisons should consider the ADUM340E series for bidirectional options or lower speed requirements. Verify package dimensions and thermal characteristics match the existing design constraints.
