ADUM242D0BRWZ

Overview

The ADUM242D0BRWZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides four independent channels with a 2:2 input-to-output configuration and unidirectional signal polarity. The device operates within a supply voltage range of 1.7V to 5.5V and supports data rates up to 150 Mb/s. Key electrical specifications include an isolation voltage of 5000 Vrms, a common-mode transient immunity (CMTI) of 75 kV/µs, and a typical propagation delay of 7.2 ns. It functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology for robust signal transmission.
• Provides high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Features unidirectional channel polarity suitable for standard logic interface applications.

Applications

• Industrial automation systems requiring galvanic isolation between control and power stages
• Medical equipment interfaces needing certified safety isolation barriers
• Power electronics gate drive circuits for inverters and motor drives

Procurement Notes

Verify the specific suffix '0BRWZ' against official Analog Devices documentation to confirm pinout and package dimensions. Confirm RoHS compliance status through current datasheets. Check for obsolescence notices or lifecycle changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a quad-channel solution with 5000 Vrms isolation is required. Ensure the 150 Mb/s data rate meets system timing requirements. Verify that the SOIC-16 package fits the PCB layout constraints. Consider the 11 mA supply current for thermal management in enclosed designs.

Part Context

This part belongs to the ADuM242 series of general-purpose digital isolators. It shares the same core iCoupler architecture as other variants in the family but differs in channel count and isolation ratings compared to dual-channel or higher-voltage models. It serves as a bridge between low-voltage logic and high-voltage domains.

Replacement Considerations

Cross-reference with ADUM242E0BRWZ for potential upgrades. Verify functional compatibility regarding pinouts and electrical parameters before substitution. Consult official Analog Devices documentation for approved alternate part numbers.
