ADUM3201ARZ

Overview

The ADUM3201ARZ is a dual-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 1 Mbps. The device provides an isolation voltage of 2500 Vrms with a common-mode transient immunity of 25 kV/µs. Key electrical parameters include a maximum propagation delay of 150 ns, typical rise and fall times of 10 ns, and a maximum pulse width distortion of 40 ns. It functions reliably across an extended temperature range from -40°C to +105°C in an 8-pin SOIC package.

Feature Summary

• Integrates two independent unidirectional channels using on-chip transformer technology for signal isolation.
• Provides enhanced system-level ESD reliability compliant with IEC 61000-4-x standards.
• Includes a patented refresh feature to maintain DC correctness during static input conditions or power transitions.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal interfaces
• Power metering and energy management circuits

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel configuration. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when bidirectional communication is not required, as it supports only unidirectional signal flow. It is suitable for applications needing moderate data speeds up to 1 Mbps rather than high-speed transmission. Consider the 8-pin SOIC footprint constraints and verify that the 2500 Vrms isolation rating aligns with the safety requirements of the specific circuit design.

Part Context

This device belongs to the ADuM320x series of dual-channel digital isolators developed by Analog Devices. It represents an evolution of earlier iCoupler products, offering improved layout and circuit performance compared to legacy models like the ADuM120x series. The technology replaces optical components with magnetic coupling to reduce power consumption and eliminate LED degradation issues.

Replacement Considerations

The ADUM3201BRZ serves as a higher-speed alternative within the same family, supporting 10 Mbps data rates while maintaining similar isolation characteristics and pin configurations.
