ADUM5202ARWZ-RL

Overview

The ADUM5202ARWZ-RL is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It integrates an isoPower isolated DC-to-DC converter, providing regulated 3.3V or 5V output with up to 400mW power capability. The device offers 2500Vrms isolation voltage and supports data rates up to 100Mbps (NRZ). Key electrical parameters include a propagation delay of 60ns, a common-mode transient immunity (CMTI) exceeding 25kV/µs, and operation within a temperature range of -40°C to +105°C. It is housed in a 16-pin SOIC package.

Feature Summary

• Integrates an isolated DC-to-DC converter for complete power and signal isolation
• Utilizes iCoupler magnetic coupling technology for high-speed digital signal transmission
• Provides high common-mode transient immunity for reliable operation in noisy environments

Applications

• Isolated sensor interfaces
• Industrial PLC communication
• RS-232 transceiver isolation
• Power supply biasing and gate driving

Procurement Notes

Verify the specific suffix configuration against the manufacturer's datasheet to ensure compatibility with required output voltage and channel directionality. Confirm that the 16-SOIC package dimensions align with the target PCB footprint. Check for automotive qualification status if the application requires AEC-Q100 compliance, as this may vary by specific sub-model variant.

Selection Notes

Select this component when a compact solution combining signal isolation and isolated power generation is required. It is suitable for applications needing high CMTI and moderate data rates up to 100Mbps. Consider the integrated converter's power limits and thermal performance under maximum load conditions. Ensure the input voltage range matches the source logic levels before implementation.

Part Context

This part belongs to the ADuM52xx series of dual-channel digital isolators with integrated isoPower converters. The series is designed to replace traditional optocouplers and discrete transformer solutions, offering superior performance in speed, size, and reliability. The ADUM5202 variant specifically provides two unidirectional channels with integrated power conversion capabilities.

Replacement Considerations

Direct replacements within the same family include ADUM5202ARWZ-RL variants with different temperature grades or packaging options. Cross-family comparisons should focus on devices offering similar integrated isolated power and dual-channel isolation specifications.
