ADUM1201WURZ55-RL7

Overview

The ADUM1201WURZ55-RL7 is a dual-channel digital isolator manufactured by Analog Devices Inc. It utilizes proprietary iCoupler magnetic coupling technology to provide electrical isolation between circuits. The device features two independent channels with a unidirectional signal flow configuration (1/1 input/output split). It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 10Mbps. Key electrical specifications include a maximum propagation delay of 50ns, a pulse width distortion of 3ns, and typical rise/fall times of 2.5ns. The component offers an isolation voltage of 2500Vrms and a common-mode transient immunity of 25kV/µs. It is housed in an 8-SOIC package with a 0.154-inch width and functions across an operating temperature range of -40°C to 125°C.

Feature Summary

• Employs iCoupler magnetic coupling technology for robust signal transmission without optical components.
• Provides high common-mode transient immunity to maintain signal integrity in noisy environments.
• Features low power consumption suitable for battery-operated systems.
• Offers bidirectional communication capability through specific channel configurations.

Applications

• Industrial automation control systems requiring galvanic isolation.
• Medical equipment needing patient isolation protection.
• Automotive electronics interfaces.
• Power metering applications.

Procurement Notes

Verify the exact suffix WURZ55 against official Analog Devices documentation to confirm pinout and packaging specifics. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm availability status as distribution listings may vary. Check for RoHS compliance and REACH registration status if required by your region. Validate that the 8-SOIC package dimensions match your assembly constraints.

Selection Notes

Select this component when high-speed digital isolation is required alongside low power consumption. The 10Mbps data rate supports fast communication protocols. The 2500Vrms isolation rating provides adequate safety margin for many industrial and medical standards. Consider the 8-SOIC package size for space-constrained designs. Evaluate the need for unidirectional versus bidirectional channels based on system architecture requirements.

Part Context

This part belongs to the ADuM1201 family of dual-channel digital isolators from Analog Devices. The family leverages silicon dioxide insulation and copper coils for isolation. Variants within the family differ primarily in data rates, channel directionality, and packaging options. The ADUM1201 series is designed to replace traditional optocouplers in many applications, offering superior performance and reliability.

Replacement Considerations

Check for direct replacements such as ADUM1201ARZ or ADUM1201WTRZ depending on packaging and reel requirements. Verify functional equivalence regarding data rate and isolation voltage before substitution. Ensure pin-to-pin compatibility if replacing on an existing board. Consult Analog Devices for updated lifecycle status and recommended alternatives if this specific suffix is obsolete.
