ADUM5210CRSZ

Overview

The ADUM5210CRSZ is a dual-channel digital isolator from Analog Devices featuring integrated isoPower technology. It provides bidirectional signal isolation with an internal isolated DC-to-DC converter, eliminating the need for external bias supplies on the secondary side. The device supports data rates up to 100 Mb/s and offers a common-mode transient immunity of 25 kV/µs. It operates within a supply voltage range of 2.7 V to 5.5 V and is housed in a 20-lead SSOP package. The component ensures reliable electrical isolation with a rated insulation voltage of 2500 Vrms.

Feature Summary

• Integrates an isolated DC-to-DC converter to provide power to the secondary side without external components.
• Provides dual-channel bidirectional digital signal isolation with high common-mode transient immunity.
• Supports data transmission speeds up to 100 Mb/s for efficient communication across isolation barriers.

Applications

• Industrial automation systems requiring galvanic isolation between control and sensor circuits.
• Medical equipment needing safe patient isolation and signal integrity.
• Power electronics interfaces for monitoring and control in high-voltage environments.

Procurement Notes

Verify the specific suffix (e.g., -RL7) against the required packaging format such as reel or cut tape. Confirm RoHS compliance status through official documentation. Check current availability as distribution may vary by region. Ensure the operating temperature range meets system requirements. Validate pinout compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when both signal isolation and secondary-side power delivery are required in a compact form factor. The integrated DC-to-DC converter simplifies design by removing external transformer and rectifier components. Consider the 100 Mb/s data rate limit for high-speed applications. Evaluate the 2500 Vrms insulation rating against system safety standards. The 20-SSOP package requires adequate thermal management for continuous operation at higher loads.

Part Context

This part belongs to the ADuM521x family of dual-channel digital isolators with isoPower. The series combines capacitive isolation technology with on-chip power conversion. Other variants in the family include ADUM5211 and ADUM5212, which differ in channel directionality. The technology enables robust isolation in space-constrained industrial and medical designs.

Replacement Considerations

Direct substitutes include ADUM5211CRSZ and ADUM5212CRSZ from the same manufacturer. These alternatives offer similar isolation characteristics but may differ in channel directionality configurations. Verify pin-to-pin compatibility and functional equivalence before substitution.
