ADUM1200BR

Overview

The ADuM1200BR is a dual-channel digital isolator utilizing iCoupler technology, integrating high-speed CMOS with monolithic transformer technology. It features 2/0 directionality and supports data rates up to 25 Mbps. The device operates on a single supply voltage ranging from 3V to 5.5V. Key electrical parameters include a maximum propagation delay of 50ns, typical rise/fall times of 2.5ns to 3ns, and a minimum common-mode transient immunity (CMTI) of 25kV/µs. It provides 2500Vrms isolation voltage and functions within an operating temperature range of -40°C to 105°C.

Feature Summary

• Integrates high-speed CMOS logic with monolithic transformer technology for signal isolation.
• Provides bidirectional communication capabilities with 3V/5V level translation support.
• Offers precise timing characteristics including low pulse-width distortion and channel matching.
• Delivers high common-mode transient immunity superior to traditional optocoupler alternatives.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal transmission across isolation barriers
• Power electronics control circuits with high noise environments

Procurement Notes

Verify the specific suffix (e.g., BRZ vs BR) against the original design specifications to ensure package compatibility and regulatory approvals match the intended application requirements. Confirm availability status as manufacturing statuses may vary by region or distributor.

Selection Notes

Select this component when bidirectional data transfer is required between isolated domains. Ensure the system power supply falls within the 3V to 5.5V range. Verify that the 2500Vrms isolation rating meets the safety standards required for the specific application environment.

Part Context

This part belongs to the ADuM120x series of dual-channel digital isolators from Analog Devices. The series leverages iCoupler technology to replace optocouplers, offering smaller form factors and lower power consumption while maintaining high reliability in harsh electromagnetic environments.

Replacement Considerations

ADUM1200WURZ is listed as a parameter-equivalent alternative. Verify pinout compatibility and package dimensions before substitution.
