ADUM5200ARWZ

Overview

The ADUM5200ARWZ is a dual-channel digital isolator from the IsoPower series, manufactured by Analog Devices Inc. It integrates an isolated DC-to-DC converter to provide power and signal isolation in a single package. The device features two unidirectional channels with a data rate of 1Mbps and a common-mode transient immunity (CMTI) of 25kV/µs. It operates within a supply voltage range of 3V to 5.5V on both sides and supports a basic isolation voltage of 2500Vrms. The component is housed in a 16-SOIC package and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Integrates an isolated DC-to-DC converter to eliminate external transformer requirements
• Provides galvanic isolation for both signal transmission and power delivery
• Utilizes iCoupler magnetic coupling technology for high reliability

Applications

• Industrial automation systems requiring isolated power and communication
• Medical equipment needing reinforced isolation barriers
• Inverters and motor control circuits with integrated isolation needs

Procurement Notes

Verify the specific suffix ARWZ corresponds to the tube packaging format and industrial temperature grade. Confirm that the 16-SOIC footprint matches the target PCB design constraints. Ensure the application environment does not exceed the specified 2500Vrms isolation rating or the maximum operating temperature of 105°C. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component when a compact solution is required for simultaneous signal isolation and isolated power generation. It is suitable for applications where space constraints prevent the use of discrete transformers and separate isolators. Consider the 1Mbps data rate limit; higher speed requirements may necessitate models from the ADuM5201 or ADuM5402 series. Evaluate the thermal performance of the SOIC package under continuous load conditions.

Part Context

This part belongs to the ADuM520x family of dual-channel digital isolators with integrated power converters. It shares the same core architecture as the ADUM5201 but offers lower data rates. The family utilizes proprietary iCoupler technology to replace traditional magnetics, reducing size and improving long-term reliability compared to optocoupler-based solutions.

Replacement Considerations

The ADUM5201ARWZ serves as a direct functional substitute offering higher data rates. For quad-channel requirements, the ADUM5402ARWZ provides similar integrated power capabilities with additional channels.
