ADUM342E0WBRQZ-RL7

Overview

The ADUM342E0WBRQZ-RL7 is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features a QSOP-16 surface-mount package and supports unidirectional data flow at speeds up to 150 Mb/s. The device operates within a supply voltage range of 2.25 V to 5.5 V with a typical operating current of 11 mA. It provides robust isolation with ratings of 3 kVrms basic insulation and 5.7 kVrms reinforced insulation. The component is designed for reliable performance across an extended temperature range.

Feature Summary

• Implements magnetic coupling architecture for high-speed digital signal isolation
• Provides four independent channels for versatile system integration
• Supports low-voltage operation compatible with modern logic families

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment needing reinforced safety barriers
• Power metering applications with high common-mode transient immunity

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to implementation. Check current availability as distribution may be limited or subject to allocation constraints. Ensure the QSOP-16 footprint matches your PCB design requirements exactly.

Selection Notes

Select this component when four isolated channels are required in a compact form factor. Consider the 150 Mb/s data rate limit for high-speed interface needs. Evaluate the 3 kVrms insulation rating against your system's safety standards. Compare power consumption characteristics against alternative isolator technologies for efficiency optimization.

Part Context

This part belongs to the ADUM342 series of digital isolators from Analog Devices. It shares the QSOP-16 package format with other members like the ADUM341 and ADUM343 variants. The series utilizes proprietary iCoupler technology for on-chip isolation barrier construction. It serves as a direct replacement for legacy optocoupler solutions in space-constrained designs.
