ADUM3200ARZ

Overview

The ADUM3200ARZ 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 1 Mb/s. The device provides 2500 Vrms isolation voltage and exhibits a typical propagation delay of 150 ns with rise/fall times of 10 ns. It features unidirectional channels in an 8-pin SOIC package, operating reliably between -40°C and +105°C.

Feature Summary

• Dual-channel unidirectional digital isolation using proprietary magnetic coupling technology
• Enhanced system-level ESD reliability for robust industrial performance
• Low power consumption with independent channel power supplies

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment signal transmission interfaces
• Power management circuit monitoring and control loops

Procurement Notes

Verify the specific suffix ARZ corresponds to the standard SOIC-8 package and commercial/industrial temperature range. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check current availability as distribution may vary by region.

Selection Notes

Select this component when bidirectional communication is not required, as it supports only unidirectional data flow. Ensure the design accommodates separate power domains for input and output sides to maintain isolation integrity. Verify that the 1 Mb/s data rate meets the application timing requirements.

Part Context

This part belongs to the ADUM3200 series of dual-channel digital isolators. It shares the same pinout and core functionality as the ADUM3201ARZ but differs in internal logic configuration. The series is designed for applications needing high-speed, low-power isolation without integrated DC-DC converters.

Replacement Considerations

ADUM3201ARZ offers similar electrical characteristics but with different logic gate configurations. ADUM1200BRZ provides higher speed capabilities but requires careful evaluation of package and parameter compatibility.
