ADUM1280BRZ-RL7

Overview

The ADUM1280BRZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides galvanic isolation with a rated insulation voltage of 3000 Vrms. The device supports bidirectional data transmission at speeds up to 100 Mb/s. It operates within a supply voltage range of 3.135 V to 5.5 V and features a typical propagation delay of 35 ns. Packaged in an 8-pin SOIC (NSOIC) surface-mount format, it is supplied in reel packaging.

Feature Summary

• Provides robust galvanic isolation between circuits using proprietary iCoupler magnetic coupling technology.
• Supports bidirectional signal transmission for flexible system design configurations.
• Delivers high-speed data integrity with a maximum data rate of 100 Mb/s.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power electronics control circuits

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the BRZ variant corresponds to the bidirectional configuration as distinct from unidirectional models. Ensure compatibility with the required 3000 Vrms isolation rating for your safety standards. Check current availability status as distribution may be limited.

Selection Notes

Select this component when bidirectional data flow is required across an isolation barrier. Compare against unidirectional variants if only one-way transmission is needed. Verify that the 100 Mb/s speed meets system timing requirements. Ensure the 8-pin SOIC package fits the PCB layout constraints.

Part Context

This part belongs to the ADUM1280 series of small, low-power digital isolators. It shares the same core iCoupler architecture but differs in channel directionality compared to other members like the ADUM1280ARZ. It serves as a general-purpose isolator for standard digital signals.

Replacement Considerations

Direct substitutes include other ADUM1280 variants such as ADUM1280ARZ-RL7, though polarity differences must be accounted for. Cross-reference pinouts and electrical specifications before substitution.
