ADUM1401BRWZ-RL

Overview

The ADUM1401BRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 10 Mb/s and an isolation voltage of 2500 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing typical power supply currents of 31 mA and 57 mA on the respective sides. Propagation delay is specified at 32 ns, with typical rise and fall times of 3 ns. It is housed in a 16-pin SOIC-W package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates high-speed CMOS logic with single-chip air-core transformer technology for robust signal transmission.
• Provides electrical isolation via magnetic coupling, eliminating the need for external components found in optical alternatives.
• Features unidirectional channel directionality to simplify circuit design for specific signal flow requirements.

Applications

• Isolated communication interfaces such as RS-485 and CAN bus systems
• General-purpose digital isolation in industrial automation equipment
• Power monitoring and control circuits requiring galvanic separation

Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm pinout and electrical specifications. Ensure the component meets RoHS compliance requirements for your region. Confirm that the reel packaging aligns with your automated assembly capabilities. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit sources.

Selection Notes

Select this component when unidirectional isolation is required for multiple digital signals simultaneously. Compare propagation delay and current consumption against bidirectional alternatives if signal direction varies. Ensure the 2500 Vrms isolation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the ADuM1400/ADuM1401/ADuM1402 family of quad-channel digital isolators. These devices are designed to replace traditional optocouplers by offering superior performance in speed, power consumption, and reliability while maintaining compact form factors suitable for modern surface-mount applications.

Replacement Considerations

Check for ADUM1401ARWZ-RL if bidirectional channels are needed instead of unidirectional. Verify ADUM1401WTRWZ-RL for automotive-grade AEC-Q100 qualification requirements. Consult official substitution guides for any changes in pin configuration or thermal characteristics.
