ADUM142E1BRWZ-RL

Digital Isolators Overview

The ADUM142E1BRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features a 150 Mb/s data rate and supports unidirectional signal transmission across four channels (2:2 configuration). The device operates within a supply voltage range of 1.7 V to 5.5 V and provides an insulation voltage of 3750 Vrms. It exhibits a propagation delay of 13 ns and a common-mode transient immunity of 75 kV/µs. The component is housed in a 16-SOIC package and functions reliably within an operating temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Integrates four independent isolation channels using proprietary iCoupler magnetic coupling technology for high-speed data transmission.
• Provides robust electrical isolation with a 3750 Vrms insulation rating and high common-mode transient immunity of 75 kV/µs.
• Supports flexible power supply operation ranging from 1.7 V to 5.5 V with low quiescent current consumption per channel.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripheral sensors.
• Medical equipment interfaces needing high-voltage isolation for patient safety compliance.
• Automotive electronic control units (ECUs) utilizing isolated communication buses such as CAN or LIN.
• Power metering applications involving isolated ADC inputs and energy measurement circuits.

Digital Isolators Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm the 'E1' designation aligns with the required 3750 Vrms insulation rating rather than lower variants. Ensure the SOIC-16 footprint matches the PCB layout constraints. Check RoHS compliance status against current regulatory requirements for the target market.

Digital Isolators Selection Notes

Select this component when a quad-channel solution with 150 Mbps speed and 3750 Vrms isolation is required. Compare against the ADUM142E0 variant if only 3000 Vrms isolation is sufficient for the application. Consider the SOIC-16 package width for board space limitations. Evaluate the 75 kV/µs CMTI specification against noise environments in industrial settings.

Digital Isolators Part Context

This part belongs to the ADuM142E family of robust quad digital isolators. It represents an evolution in iCoupler technology, offering higher isolation ratings compared to earlier generations like the ADUM1402. The series is designed for general-purpose isolation in demanding environments where reliability and speed are critical.

Digital Isolators Replacement Considerations

The ADUM142E1BRQZ is a pin-compatible alternative available in a QSOP package. Verify that the package dimensions and thermal characteristics of the substitute match the existing design constraints before implementation.
