ADUM342E0BRWZ-RL

Overview

The ADUM342E0BRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler technology with integrated CMOS and monolithic transformer coupling. It features bidirectional data transmission at a maximum data rate of 150 Mb/s. The device operates on a supply voltage range of 2.25 V to 5.5 V and provides an insulation voltage of 10 kV peak. It is housed in a 16-lead SOIC package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Integrates four independent bidirectional data channels using magnetic coupling technology for robust signal isolation.
• Provides high common-mode transient immunity to suppress noise interference in electrically noisy environments.
• Supports flexible logic levels with input/output pin compatibility across the specified voltage range.

Applications

• Isolation for serial peripheral interface (SPI) communication lines
• Signal isolation in RS-485 and Controller Area Network (CAN) systems
• Isolating pulse-width modulation (PWM) controller signals

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct channel directionality and default output states. Confirm that the bidirectional nature aligns with system requirements. Check for updated regulatory certifications such as UL or VDE compliance before final integration. Ensure the operating temperature range meets environmental specifications.

Selection Notes

Select this component when bidirectional data flow is required across all four channels within a single package. It is suitable for applications needing high-speed data rates up to 150 Mb/s with strong noise immunity. Consider the 10 kV peak insulation rating for high-voltage isolation needs. Evaluate power consumption at the target data rate to ensure it fits thermal constraints.

Part Context

This part belongs to the ADuM34xE series of quad-channel digital isolators. The series leverages silicon dioxide-based isolation technology to replace traditional optocouplers. It offers superior performance in speed, power consumption, and size compared to legacy isolation methods. The E0 suffix indicates a specific logical configuration for the outputs.

Replacement Considerations

Check for ADUM342E1BRWZ-RL if unidirectional channels are acceptable. Verify ADUM3402 variants for lower data rate requirements. Ensure any substitute maintains the 16-pin SOIC footprint and compatible insulation ratings.
