ADUM3211BRZ

Overview

The ADUM3211BRZ is a dual-channel digital isolator utilizing Analog Devices iCoupler technology, which integrates high-speed CMOS logic with monolithic transformer coupling on a single silicon substrate. This component provides electrical isolation for bidirectional data transmission across isolated boundaries. 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 features a propagation delay of 50 ns and offers an insulation voltage rating of 2500 Vrms. It is housed in an 8-pin SOIC package and is designed for general-purpose signal isolation applications requiring enhanced system-level ESD reliability.

Feature Summary

• Integrates high-speed CMOS logic with monolithic on-chip transformer coupling technology for compact signal isolation
• Provides robust galvanic isolation between input and output sides without external magnetic components
• Supports unidirectional data transmission channels with enhanced system-level electrostatic discharge protection

Applications

• General-purpose signal isolation in industrial automation systems
• Isolation barriers in power monitoring and control circuits
• Data communication interfaces requiring galvanic separation

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as availability may vary by region. Confirm that the component meets required RoHS compliance standards for your target market. Check current distribution status as some variants may be subject to limited supply or factory special orders. Ensure the selected part number matches the exact pinout and thermal requirements of your design.

Selection Notes

Select this component for designs requiring dual-channel isolation with moderate data rates up to 10 Mb/s. Consider the 8-SOIC package dimensions for PCB layout constraints. Evaluate the 2500 Vrms insulation rating against the specific isolation voltage requirements of the application. Compare propagation delay specifications if timing sensitivity is critical for the data interface being isolated.

Part Context

This component belongs to the ADuM321x series of dual-channel digital isolators from Analog Devices. The series leverages iCoupler technology to replace traditional optocouplers and magnetic couplers. These devices are categorized under interface ICs and are designed to offer superior performance in terms of size, speed, and reliability compared to legacy isolation technologies.

Replacement Considerations

The ADUM1201WTRZ is listed as a parameter-equivalent alternative within the manufacturer's portfolio. Verify compatibility regarding package type and electrical specifications before substitution.
