ADUM120N0BRZ-RL7

Overview

The ADUM120N0BRZ-RL7 is a dual-channel digital isolator from Analog Devices, housed in an SOIC-8 package. It provides 3000 Vrms isolation voltage with magnetic coupling technology. The device supports unidirectional data transmission at speeds up to 150 Mb/s and features a minimum common-mode transient immunity of 75 kV/µs. It operates on supply voltages ranging from 1.7 V to 5.5 V, drawing approximately 6.2 mA of operating current. Key timing parameters include a propagation delay of 7.2 ns and tight channel matching with a maximum skew of 3.0 ns.

Feature Summary

• Provides robust electromagnetic interference (EMC) immunity through high common-mode transient resistance.

Applications

• Industrial communication interfaces requiring galvanic isolation
• Medical equipment signal isolation
• Power management circuit monitoring

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm RoHS compliance status via official documentation before integration. Ensure the supplier source is authorized to guarantee component authenticity and traceability for critical applications.

Selection Notes

Select this component for designs requiring high-speed data rates exceeding standard isolators while maintaining compact SOIC-8 footprint. Consider the 1.7 V to 5.5 V supply range for compatibility with various logic families. Evaluate the 75 kV/µs CMTI rating against noise environments in industrial settings.

Part Context

This part belongs to the ADUM120N series, which focuses on EMC robustness. It differs from other ADUM variants by offering higher data rates and superior transient immunity compared to lower-speed counterparts in the same family.

Replacement Considerations

Check ADUM120N0BRZ for tube packaging alternatives. Verify ADUM1200 or ADUM1201 series only if lower data rates are acceptable, as they do not match the 150 Mb/s specification.

FAQ
