ADUM5210ARSZ

Overview

The ADUM5210ARSZ is a dual-channel digital isolator from Analog Devices, featuring integrated isoPower DC-to-DC converters. It provides bidirectional signal isolation with data rates up to 100 Mbps and an insulation voltage of 2500 Vrms. The device operates within a supply voltage range of 3.135 V to 5.5 V and supports propagation delays as low as 15 ns. Designed for robust performance, it offers high common-mode transient immunity and functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Integrates isolated DC-to-DC converters for independent side power supplies
• Provides dual-channel bidirectional signal isolation via magnetic coupling
• Supports high-speed data transmission at rates up to 100 Mbps
• Ensures reliable operation with high common-mode transient immunity

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation barriers
• Isolated RS-485 and CAN communication interfaces
• Smart grid and metering applications

Procurement Notes

Verify the specific suffix 'ARSZ' corresponds to the SSOP-20 package and reel packaging configuration when sourcing. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure compatibility with the intended operating voltage range of 3.135 V to 5.5 V during design validation. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit or obsolete variants.

Selection Notes

Select this component when both signal isolation and isolated power generation are required in a compact form factor. The integrated DC-to-DC converter eliminates the need for external isolated power supplies, simplifying board layout. Consider the 100 Mbps data rate capability for high-speed serial communication needs. Evaluate the thermal performance requirements against the specified -40°C to +105°C operating range for environmental suitability.

Part Context

This part belongs to the ADUM5210 series of dual-channel digital isolators. It is distinct from unidirectional variants like the ADUM5211 and single-channel models. The series utilizes capacitive and magnetic coupling technologies to achieve high isolation voltages while maintaining small footprint dimensions suitable for dense PCB layouts.

Replacement Considerations

Direct substitutes include other ADUM521x series devices with matching channel counts and isolation ratings. Verify pinout compatibility and electrical specifications before swapping with similar products from different manufacturers. Check datasheet revisions for any changes in recommended operating conditions.
