ADUM1400WTRWZ35

Overview

The ADUM1400WTRWZ35 is a four-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It provides electrical isolation with a rating of 2500 Vrms across four unidirectional channels, configured as 4Tx/0Rx. The device operates on a supply voltage range of 2.7V to 5.5V and supports data rates up to 1Mbps. Key performance metrics include a maximum propagation delay of 100ns, rise/fall times of 2.5ns, and a minimum common-mode transient immunity (CMTI) of 25kV/µs. It is housed in a 16-lead SOIC package and is qualified under the AEC-Q100 automotive standard.

Feature Summary

• Integrates four isolated signal channels using proprietary iCoupler magnetic coupling technology for high-speed data transmission.
• Provides robust signal integrity with a minimum common-mode transient immunity of 25kV/µs.
• Eliminates design complexities associated with traditional optocouplers by removing the need for external drivers or discrete components.
• Meets automotive reliability standards through AEC-Q100 qualification.

Applications

• Automotive electronic control units requiring galvanic isolation
• Industrial communication interface isolation
• Power monitoring systems with high-voltage separation needs

Procurement Notes

Verify that the specific suffix '35' corresponds to the required tape-and-reel packaging configuration, as this variant differs from standard tube-packaged models like the ADUM1400WSRWZ. Confirm the component's active status and availability directly with authorized distributors, as lead times may vary. Ensure the selected part matches the intended application's thermal and voltage requirements before finalizing procurement.

Selection Notes

Select this component when four independent unidirectional isolation channels are required within a single package. It is suitable for applications demanding high CMTI resistance and low power consumption compared to optical isolators. Consider the 16-SOIC footprint and AEC-Q100 qualification if automotive compliance is necessary. Evaluate the 1Mbps data rate limit against system speed requirements.

Part Context

This device belongs to the ADUM1400 series of iCoupler digital isolators. It shares core architectural features with variants such as the ADUM1400WSRWZ but differs in packaging format. The series is designed to replace optocouplers in various interface applications, offering superior consistency and lower power usage while maintaining high isolation voltages.

Replacement Considerations

For direct parameter-equivalent replacements, consider the ADUM1400WTRWZ. Verify compatibility regarding channel count, isolation voltage, and data rate before substitution.
