ADUM5210ARSZ-RL7

Overview

The ADUM5210ARSZ-RL7 is a dual-channel digital isolator from Analog Devices, featuring integrated DC-to-DC converters for power delivery across isolation barriers. It utilizes magnetic coupling technology to provide electrical isolation with a rated insulation voltage of 2500 Vrms. The device supports unidirectional data transmission at speeds up to 100 Mb/s and exhibits a propagation delay of 15 ns. Designed for robust industrial environments, it operates within a temperature range of -40°C to +105°C. The component is housed in an SSOP-20 package and functions on a supply voltage of 5.5 V.

Feature Summary

• Integrates isolated DC-to-DC converters to eliminate external transformer requirements
• Employs capacitive and magnetic coupling for high-speed signal and power isolation
• Provides bidirectional communication capability through dual independent channels

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced safety isolation
• Power electronics monitoring circuits

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SSOP-20 footprint matches your PCB layout constraints. Check current availability as distribution may vary by region.

Selection Notes

Select this component when both signal isolation and isolated power generation are required in a compact form factor. The integrated converter simplifies design compared to discrete solutions. Verify that the 100 Mb/s data rate meets system timing requirements. Ensure the 2500 Vrms isolation rating satisfies safety standards for the target application environment.

Part Context

This part belongs to the ADuM5210 series of dual-channel isolators. It shares architectural similarities with other members like the ADUM5211 but differs in channel configuration or pinout. The series represents Analog Devices' approach to combining high-speed digital isolation with efficient power management in a single IC package.

Replacement Considerations

Direct substitutes include ADUM5210CRSZ-RL7 which shares identical electrical specifications but may differ in manufacturing lot or regional distribution details. Cross-reference datasheets to confirm pin compatibility and thermal performance before substitution.
