ADUM342E0WBRWZ-RL

Overview

The ADUM342E0WBRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing capacitive coupling technology for signal transmission. It features four bidirectional channels with a data rate of 150 Mb/s and an insulation voltage of 5700 Vrms. The device operates on a supply voltage range of 2.25 V to 5.5 V and consumes 7.3 mA of operating current. Packaged in a 16-pin QSOP format, it supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Employs capacitive coupling technology for robust signal isolation
• Provides four independent bidirectional communication channels
• Supports high-speed data transmission up to 150 Mb/s
• Features high common-mode transient immunity for noise rejection

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation barriers
• Power management circuits with isolated feedback loops
• Gate driver interfaces for power semiconductor switching

Procurement Notes

Verify the specific suffix 'W' indicates the QSOP-16 package variant distinct from standard SOIC packages. Confirm availability status as limited supply or special order may apply. Ensure compatibility with 2.25V to 5.5V logic levels. Check for AEC-Q100 qualification if automotive applications are intended. Validate pinout alignment against schematic requirements before integration.

Selection Notes

Select this component when bidirectional data flow is required across all four channels. Choose based on the need for 5700 Vrms isolation strength in compact QSOP packaging. Consider the 150 Mb/s speed for high-bandwidth serial communications. Evaluate power consumption at 7.3 mA against system energy constraints. Compare against unidirectional alternatives if channel directionality can be simplified.

Part Context

This part belongs to the ADuM34xE family of quad digital isolators designed for high-performance isolation applications. It integrates four independent channels within a single small outline package. The series emphasizes low power consumption and high reliability for industrial and medical environments. It serves as a critical interface between isolated and non-isolated circuit domains.

Replacement Considerations

Public confirmed substitute part numbers: ADUM342E0BRWZ (SOIC-16 package variant), ADUM340E1BRWZ-RL (unidirectional variant). Verify package dimensions and pinout compatibility before substitution.
