ADUM1401WSRWZ35-RL

Overview

The ADUM1401WSRWZ35-RL is a quad-channel digital isolator manufactured by Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and provides an isolation voltage of 2500 Vrms. The device supports data rates up to 1 Mbps with a maximum propagation delay of 100 ns and a minimum common-mode transient immunity of 25 kV/µs. It features a 3:1 channel configuration (three transmitters, one receiver) in a 16-pin SOIC package. Qualified under AEC-Q100 standards, it functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates four independent digital channels using proprietary iCoupler magnetic coupling technology for signal transmission across isolation barriers.
• Provides robust protection against high-voltage transients with a specified common-mode transient immunity of 25 kV/µs.
• Features unidirectional signal flow capability with a specific 3-transmitter to 1-receiver channel architecture.
• Complies with automotive reliability standards through AEC-Q100 qualification for extended industrial temperature operation.

Applications

• Isolated communication interfaces in automotive electronic control units
• Signal isolation in industrial measurement and control systems
• Power monitoring circuits requiring galvanic separation
• Motor drive gate driver isolation

Procurement Notes

Verify the suffix '35' corresponds to the specific moisture sensitivity level or packaging variant required for your assembly process. Confirm that the 1 Mbps data rate meets system timing requirements, as higher-speed variants exist within the family. Ensure the 2500 Vrms isolation rating satisfies the safety regulations applicable to your target market. Cross-reference the SOIC-16 footprint dimensions during PCB layout to ensure compatibility with existing designs.

Selection Notes

Select this component when a quad-channel isolator with a 3:1 directional configuration is required. It is suitable for applications needing moderate data speeds where low power consumption and high reliability are prioritized over maximum throughput. Consider alternative models if bidirectional communication or higher data rates exceeding 1 Mbps are necessary. Verify that the 2.7 V to 5.5 V supply range aligns with the logic levels of the interfacing devices.

Part Context

This part belongs to the ADUM1401 series of iCoupler digital isolators from Analog Devices. The series leverages silicon dioxide insulation layers on CMOS chips to provide electrical isolation without the need for optical components or transformers. This technology offers superior performance in terms of size, power consumption, and reliability compared to traditional optocouplers, making it a standard choice for modern isolated interface designs.
