ADUM241D0BRWZ

Overview

The ADUM241D0BRWZ is a robust quad digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent channels configured as three forward and one reverse unidirectional path. The device operates with 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 typical propagation delay of 7.2 ns, and a common-mode transient immunity of 75 kV/µs. It functions within a temperature range of -40°C to +125°C and is housed in a 16-pin SOIC package.

Feature Summary

• Provides galvanic isolation via on-chip transformer technology for noise immunity
• Supports high-speed digital signal transmission with low latency
• Ensures safety compliance through high dielectric breakdown voltage ratings

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics control circuits with high-voltage separation needs

Procurement Notes

Verify the specific suffix 'D0' against the official Analog Devices datasheet to confirm channel configuration and logic polarity. Ensure the SOIC-16 package dimensions match the target PCB footprint. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Check for RoHS compliance status if required by regional regulations.

Selection Notes

Select this component when a quad-channel isolator with asymmetric 3:1 directionality is required. It is suitable for applications demanding high common-mode transient immunity and wide operating voltage ranges. Consider the 16-SOIC package size for space-constrained designs. Evaluate power consumption relative to system battery life or thermal constraints.

Part Context

This part belongs to the ADuM241 series of robust iCoupler digital isolators. The series is designed for harsh environments where traditional optocouplers may fail due to aging or noise sensitivity. The ADUM241D0 variant specifically offers a fixed 3-forward, 1-reverse channel configuration.

Replacement Considerations

ADUM241E1BRIZ is a documented parameter-equivalent alternative within the same family. Verify that the E1 suffix does not alter the functional logic or pinout before substitution.
