ADUM342E0BRQZ-RL7

Overview

The ADUM342E0BRQZ-RL7 is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It features a 150 Mb/s data rate and unidirectional polarity across four channels, configured as two forward and two reverse paths. The device operates within a supply voltage range of 2.25 V to 5.5 V, drawing a typical operating current of 7.3 mA. It provides robust isolation with ratings of 3 kVrms and 5.7 kVrms insulation voltage. Key timing parameters include a propagation delay of 6.2 ns, pulse width of 6.6 ns, and pulse width distortion of 0.3 ns. The component is housed in a QSOP-16 package, supports surface mount installation, and functions reliably within an extended temperature range of -40°C to +125°C.

Feature Summary

• Integrates four independent digital isolation channels using proprietary magnetic coupling architecture.
• Delivers high-speed data transmission capability at rates up to 150 Mb/s per channel.
• Ensures electrical safety through dual-rated insulation voltage specifications for enhanced barrier integrity.
• Maintains signal fidelity with low propagation delay and minimal pulse width distortion characteristics.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing galvanic isolation for patient safety compliance
• Power electronics control circuits demanding noise immunity in high-voltage environments

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging configuration when sourcing. Confirm QSOP-16 package compatibility with PCB footprint requirements. Check moisture sensitivity level handling procedures during storage and assembly. Ensure voltage supply rails align with the 2.25 V minimum and 5.5 V maximum operational limits. Validate thermal management strategies for the specified power dissipation under maximum load conditions.

Selection Notes

Choose this component when bidirectional or multi-channel isolation is required within a single compact package. Consider the 150 Mb/s speed for applications exceeding standard UART or SPI limitations. Evaluate the 3 kVrms/5.7 kVrms ratings against system creepage and clearance needs. Compare power consumption against other isolators if battery life is critical. Assess the extended temperature range suitability for harsh industrial or automotive environments.

Part Context

This part belongs to the ADUM342 series of quad-channel digital isolators by Analog Devices. It complements lower-channel variants like the ADUM3201 while offering higher integration than dual-channel solutions. The series leverages iCoupler technology to replace traditional optocouplers, providing superior reliability and smaller form factors. It fits into designs requiring robust isolation between microcontrollers, sensors, and power stages.
