ADUM5200CRWZ-RL

Overview

The ADUM5200CRWZ-RL is a dual-channel digital isolator from Analog Devices, featuring an integrated DC/DC converter for power delivery across the isolation barrier. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mb/s. The device provides 2500 Vrms insulation strength via magnetic coupling technology. Key electrical parameters include a propagation delay of 60 ns, a typical rise/fall time of 2.5 ns, and a maximum pulse width distortion of 40 ns. It functions reliably in temperatures from -40°C to +105°C and is housed in a 16-pin SOIC_W package.

Feature Summary

• Integrates a high-efficiency DC/DC converter to provide isolated power to the secondary side, eliminating the need for external isolated supplies.
• Utilizes iCoupler magnetic coupling technology to achieve robust signal isolation with high common-mode transient immunity.
• Supports unidirectional data transmission with low propagation delay for precise timing in digital communication interfaces.

Applications

• Industrial automation systems requiring galvanic isolation between control logic and field devices.
• Medical equipment needing safe separation between patient-connected circuits and system electronics.
• Power metering applications involving high-voltage sensing and data acquisition.

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when ordering. Confirm that the component meets RoHS standards as specified in the manufacturer documentation. Ensure compatibility with the target PCB footprint for the 16-SOIC package. Check for any moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when a dual-channel isolator with integrated power conversion is required. It is suitable for designs needing 2500 Vrms isolation without external transformer components. Consider the 25 Mb/s data rate limit and 60 ns propagation delay against system timing requirements. Evaluate the 3 V to 5.5 V operating range for compatibility with existing logic levels.

Part Context

This part belongs to the ADUM5200 series of dual-channel digital isolators. It shares the same core architecture and pinout with the non-reel variant ADUM5200CRWZ, differing only in packaging format. The series is designed for applications demanding high reliability and compact solutions for signal and power isolation.

Replacement Considerations

The ADUM5200CRWZ is the direct non-tape-and-reel equivalent. For higher isolation ratings, consider the ADUM6201CRWZ-RL (5 kV). For quad-channel needs, the ADUM5403CRWZ-RL or ADUM6400CRWZ-RL may be appropriate substitutes.
