ADUM342E1WBRWZ-RL

Overview

The ADUM342E1WBRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent channels with unidirectional signal transmission and supports data rates up to 150 Mb/s at 5 V operation. The device provides isolation voltages of 3 kVrms or 5.7 kVrms depending on the specific configuration. Operating supply voltage ranges from 2.25 V to 5.5 V, enabling level shifting across the isolation barrier. It operates within a temperature range of -40°C to +125°C and is housed in a 16-pin QSOP package.

Feature Summary

• High common-mode transient immunity for robust noise rejection
• Independent channel configuration for flexible system design
• Low propagation delay and minimal pulse width distortion
• Integrated power management with low dynamic consumption

Applications

• Industrial automation control systems
• Inverter motor drives
• Power supply feedback loops
• General-purpose isolated communication interfaces

Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package variant matches QSOP-16 specifications. Validate insulation ratings against application safety requirements. Check supply chain restrictions for current region availability. Ensure ordering suffix aligns with reel packaging requirements.

Selection Notes

Select this model for applications requiring high-speed bidirectional data transfer across isolation barriers. Consider the 5.7 kVrms rating for enhanced safety compliance. Evaluate power consumption profiles for battery-operated systems. Verify thermal performance within the specified operating temperature range. Assess channel independence needs for complex signal routing.
