ADUM5211CRSZ

Overview

The ADUM5211CRSZ is a dual-channel digital isolator from Analog Devices, featuring an integrated isoPower isolated DC-to-DC converter. It provides bidirectional data isolation with a maximum data rate of 100 Mb/s and a propagation delay of 15 ns. The device supports a supply voltage range of 3.135 V to 5.5 V and operates within a temperature range of -40°C to +105°C. It offers 2500 Vrms insulation strength and 25 kV/µs common-mode transient immunity. Packaged in a 20-lead SSOP, it draws 15 mA or 15.6 mA depending on the side.

Feature Summary

• Integrates an isolated DC-to-DC converter to eliminate external transformer requirements
• Provides high-speed bidirectional data transmission up to 100 Mbps
• Delivers robust galvanic isolation with 2500 Vrms rating
• Ensures signal integrity with 25 kV/µs common-mode transient immunity

Applications

• Industrial automation systems requiring isolated communication
• Medical equipment needing safety-certified isolation barriers
• Power metering applications for current and voltage sensing
• Inverter drives and motor control circuits

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status through the manufacturer's latest datasheet. Check for obsolescence notices or lifecycle changes directly from the supplier before finalizing procurement plans.

Selection Notes

Select this component when a compact solution is needed that combines dual-channel isolation with power delivery in a single package. It is suitable for designs requiring high CMTI and low propagation delay without external magnetics. Ensure the input/output voltage levels match the system requirements within the specified 3.135 V to 5.5 V range.

Part Context

This part belongs to the ADuM521x family of digital isolators. These devices utilize iCoupler technology to provide isolation using microtransformers. The series is designed for applications demanding high reliability and small form factors, replacing traditional optocouplers and discrete isolation solutions in modern electronic designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM521x family, such as the ADUM5212, which may offer different channel configurations or power characteristics. Verify that any substitute maintains the same 20-SSOP footprint and electrical isolation ratings.
