ADUM3200BRZ-RL7

Overview

The ADUM3200BRZ-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 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 50 ns, typical rise/fall times of 2.5 ns, and a pulse width distortion of 3 ns. It functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Employs iCoupler magnetic coupling technology for signal transmission without optical or transformer-based components.
• Provides enhanced system-level ESD reliability compared to traditional digital isolators.
• Features bidirectional channel configuration with unidirectional signal flow capability.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-reliability signal isolation
• Power metering applications with isolated communication interfaces

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm current availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the SOIC-8 package variant matches the design footprint requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component for designs requiring robust isolation in noisy environments due to its high CMTI rating. Consider the 10 Mb/s data rate limit when evaluating higher-speed interface needs. The wide operating temperature range makes it suitable for harsh industrial settings. Verify power consumption constraints against the specified operating supply currents for both channels.

Part Context

This part belongs to the ADUM3200 series of dual-channel digital isolators. It shares the same core functionality as the tube-packaged ADUM3200BRZ but differs in shipping format. The series is designed to replace optocouplers in many applications while offering superior performance metrics.

Replacement Considerations

ADUM1200BRZ is listed as a parameter-equivalent alternative by distributors.
