ADUM3480BRSZ-RL7

Overview

The ADUM3480BRSZ-RL7 is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides four unidirectional signal paths with a maximum data rate of 25 Mbps and a typical propagation delay of 33 ns at 5 V. The device offers an insulation voltage of 3750 Vrms and supports a supply voltage range from 3 V to 5.5 V. Operating temperatures span from -40°C to +125°C. It is housed in a 20-pin SSOP package.

Feature Summary

• Integrates four independent unidirectional signal channels within a single compact package.
• Employs iCoupler magnetic coupling technology for high-speed digital isolation without external magnetics.
• Provides robust electrical isolation with a 3750 Vrms insulation rating.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing galvanic isolation for safety compliance
• Power electronics monitoring circuits

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the BRSZ designation matches the required SSOP-20 footprint and lead form. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit risks.

Selection Notes

Select this component when four unidirectional isolated channels are required. It is suitable for applications demanding 3750 Vrms isolation strength. Consider the 25 Mbps data rate limit for signal speed requirements. The wide operating temperature range supports harsh industrial environments.

Part Context

This part belongs to the ADuM348x series of general-purpose digital isolators. It is designed as a drop-in replacement for optical couplers in many legacy designs. The series leverages silicon dioxide insulation layers for reliability.

Replacement Considerations

Check for direct equivalents such as the ADUM3481 or ADUM3482 if bidirectional functionality or different pinouts are needed. Verify compatibility with existing PCB layouts before substitution.
