ADUM5201CRWZ

Overview

The ADUM5201CRWZ is a dual-channel digital isolator from the Analog Devices ADUM5201 series, housed in a 16-lead SOIC package. It features integrated isoPower technology for isolated DC-to-DC conversion. Key electrical parameters include a data rate of 25 Mb/s, unidirectional channel polarity, and an insulation voltage of 2500 Vrms using magnetic coupling. The device operates on a supply voltage range of 3 V to 5.5 V with a maximum propagation delay of 60 ns. It is qualified under AEC-Q100 standards and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates an isolated DC-to-DC converter to provide power across the isolation barrier without external components.
• Utilizes iCoupler magnetic coupling technology for high-speed digital signal transmission.
• Provides robust galvanic isolation with high common-mode transient immunity capabilities.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safety-certified signal isolation
• Automotive electronics compliant with AEC-Q100 standards

Procurement Notes

Verify the specific suffix (e.g., CRWZ vs. CRWZ-RL) to confirm packaging type, as tube and reel variants share identical electrical specifications but differ in shipping units. Confirm AEC-Q100 qualification status if automotive application is required. Check moisture sensitivity level handling requirements during assembly. Ensure the selected variant matches the required lead time and availability constraints.

Selection Notes

Select this component when bidirectional isolation is not required due to its unidirectional channel design. Choose the ADUM5201 over the ADUM5200 if higher data rates up to 25 Mb/s are necessary. Consider the integrated power supply feature to simplify board layout compared to discrete isolators. Verify that the 16-SOIC package dimensions fit the target PCB footprint.

Part Context

This part belongs to the ADUM5201 family of dual-channel isolators with integrated power supplies. It complements the ADUM5200, which offers lower speed but potentially different pinout or performance characteristics. The series represents Analog Devices' iCoupler technology, combining magnetic isolation with CMOS logic for compact, reliable signal transmission in noisy environments.

Replacement Considerations

The ADUM5201CRWZ-RL is the reel-packaged equivalent with identical electrical performance. Cross-reference with ADUM5200ARWZ only if lower data rates are acceptable and pin compatibility is verified. No direct functional substitutes exist within the same package without redesigning the isolation barrier.
