ADUM5202ARWZ

Overview

The ADUM5202ARWZ is a dual-channel digital isolator featuring an integrated isoPower isolated DC-to-DC converter. It provides bidirectional signal isolation with data rates up to 100 Mbps and supports SPI frequencies up to 15 MHz. The device offers 2300 Vrms basic isolation voltage and a common-mode transient immunity of greater than 25 kV/µs. Operating on a single 3V to 5.5V supply, it delivers up to 150 mW of regulated output power from its internal converter. Housed in a 16-pin SOIC package, it functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates an isolated DC-to-DC converter to eliminate external transformer requirements
• Provides high-speed digital signal isolation for dual channels
• Delivers regulated isolated power output up to 150 mW
• Ensures robust noise immunity with high common-mode transient rejection

Applications

• RS-232 transceiver interfaces
• Isolated sensor interfaces
• Industrial PLC communication modules
• Power supply bias and gate drive circuits

Procurement Notes

Verify the specific suffix 'ARWZ' corresponds to the tube packaging variant rather than the reel option. Confirm that the required isolation voltage rating meets the 2300 Vrms specification for your safety standards. Ensure the PCB footprint matches the 16-SOIC dimensions provided in the official mechanical drawings. Check for RoHS compliance status if restricted substances are a constraint.

Selection Notes

Select this component when a compact solution requires both signal isolation and isolated power generation in a single package. It is suitable for designs where space constraints prevent the use of separate magnetics for power conversion. Consider the 100 Mbps data rate limit when evaluating higher-speed interface requirements. Verify that the 150 mW output capability suffices for the downstream circuit load.

Part Context

This part belongs to the ADuM52xx series of dual-channel isolators utilizing iCoupler technology. The series combines magnetic coupling for signals with an integrated transformer for power transfer. This integration simplifies board layout by removing the need for external isolated power supplies while maintaining galvanic isolation barriers.

Replacement Considerations

The ADUM5202ARWZ-RL serves as the identical functional alternative packaged in a tape-and-reel format instead of tubes.
