ADUM242E1BRWZ

Overview

The ADUM242E1BRWZ is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides four independent channels with a 2:2 input-to-output configuration in a 16-pin SOIC package. The device supports data rates up to 150 Mbps and offers a minimum common-mode transient immunity of 75 kV/µs. It operates on a single power supply ranging from 1.7 V to 5.5 V, with a typical quiescent current of 11 mA per side. The isolation voltage rating is 5000 Vrms, and it functions within an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates four isolated channels using proprietary iCoupler silicon transformer technology for robust signal transmission.
• Provides high common-mode transient immunity to withstand rapid voltage changes across the isolation barrier.
• Supports bidirectional communication through a symmetric 2:2 channel architecture.
• Operates reliably across extended industrial temperature ranges without requiring external components.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors
• Medical equipment needing safe patient isolation interfaces
• Power electronics control circuits demanding high-voltage noise rejection

Procurement Notes

Verify the specific suffix BRWZ confirms the wide-body SOIC-16 package and tube packaging format. Confirm RoHS compliance status and moisture sensitivity level requirements against your assembly process specifications. Ensure the 5000 Vrms isolation rating meets your system safety standards before finalizing procurement.

Selection Notes

Select this component when a quad-channel solution with 5000 Vrms isolation is required. Compare propagation delay and power consumption against other iCoupler variants if lower latency or reduced current draw is critical. Ensure the 16-SOIC footprint fits your PCB layout constraints and thermal management strategy.

Part Context

This part belongs to the ADuM242E series of general-purpose digital isolators. It shares architectural similarities with the ADUM242D but features enhanced performance characteristics suitable for harsh environments. The series leverages Analog Devices' monolithic integration capabilities to replace traditional optocouplers in space-constrained designs.

Replacement Considerations

Publicly confirmed substitutes include the ADUM242E0BRWZ for identical pinout and function with potential minor parameter variations. The ADUM242E1BRIZ-RL serves as a reel-based alternative with the same electrical specifications but different packaging.
