ADUM1200WURZ55-RL7

Overview

The ADUM1200WURZ55-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features 2/0 directionality with two transmitters and zero receivers. The device operates on a supply voltage range of 2.7 V to 5.5 V. Key electrical parameters include a data rate of 25 Mb/s, an insulation voltage of 2500 Vrms, and a typical propagation delay of 45 ns. It draws 4.3 mA of operating current and functions within a temperature range of -40°C to +125°C. The component is housed in an SOIC-8 package.

Feature Summary

• Implements iCoupler technology for high-speed digital isolation using magnetic coupling.
• Provides unidirectional signal transmission with two channels and no reverse path.
• Offers robust isolation performance suitable for demanding industrial environments.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safe patient isolation
• Power metering applications with high voltage separation

Procurement Notes

Verify the specific suffix '55' against official Analog Devices documentation to confirm it denotes a valid manufacturing code or special variant distinct from standard REEL/CUT TAPE packaging. Ensure compatibility with AEC-Q100 qualification requirements if automotive use is intended. Confirm moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this component when bidirectional communication is not required, as it lacks receiver channels. Compare propagation delay specifications against system timing constraints. Evaluate power consumption relative to other iCoupler variants if battery life is critical. Ensure the SOIC-8 footprint matches the PCB design layout.

Part Context

This part belongs to the ADUM1200 series of dual-channel digital isolators. It shares the core iCoupler architecture with related models like ADUM1201 but differs in channel directionality. The series is designed for general-purpose isolation in interface circuits where noise immunity and small form factor are priorities.

Replacement Considerations

ADUM1200WURZ-RL7: Standard reel version of the same functional device. ADUM1200WSRZ: Tube packaged variant with identical electrical characteristics. Verify pinout and thermal performance match before substitution.
