ADUM3201BRZ-RL7

Overview

The ADUM3201BRZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 10 Mb/s. The device provides 2500 Vrms isolation voltage and features a common-mode transient immunity of 25 kV/µs. Key electrical parameters include a maximum propagation delay of 50 ns, typical rise and fall times of 2.5 ns, and a working supply current of 3.1 mA. It is housed in an 8-SOIC package with a wide operating temperature range.

Feature Summary

• Dual-channel unidirectional signal transmission using magnetic coupling
• Enhanced system-level ESD reliability compliant with IEC 61000-4-x standards
• Low power consumption suitable for energy-efficient designs
• High common-mode transient immunity for noisy environments

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering and smart grid interfaces
• General-purpose isolated communication links

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Ensure the component matches the 8-SOIC footprint requirements for your PCB layout. Check for any recent product change notices regarding manufacturing site updates.

Selection Notes

Select this component for applications requiring bidirectional data isolation at moderate speeds. Compare against higher-speed variants like the ADUM3201TRZ-EP if data rates exceed 10 Mb/s are needed. Consider the SOIC-8 package constraints versus wider body options. Evaluate power budget requirements against the 3.1 mA supply current specification.

Part Context

This part belongs to the ADUM3201 series of dual-channel digital isolators. It shares the core iCoupler architecture with other variants differing primarily in speed grades and packaging formats. The BRZ designation typically denotes the commercial grade performance level within the family.

Replacement Considerations

The ADUM3201BRZ is the tube-packaged equivalent of this reel-part. For higher speed requirements, the ADUM3201TRZ-EP offers 25 Mb/s capability. Verify pinout compatibility before substituting with other dual-channel isolators.
