ADUM1402CRWZ-RL

Overview

The ADUM1402CRWZ-RL is a quad-channel digital isolator utilizing iCoupler technology, housed in a 16-pin SOIC-W package. It supports a data rate of 90 Mbps with a typical propagation delay of 32 ns and isolation voltage of 2500 Vrms. The device operates on a supply voltage range of 2.7 V to 5.5 V, featuring a nominal supply current of 11 mA. It provides 25 kV/µs common-mode transient immunity and functions within an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent digital channels for bidirectional signal isolation
• Utilizes iCoupler magnetic coupling technology for high reliability
• Provides robust common-mode transient immunity against noise
• Supports flexible logic levels via wide supply voltage range

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power electronics gate drive interfaces
• Data acquisition systems requiring galvanic isolation

Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and 'RL' denotes tape-and-reel packaging. Confirm the manufacturer is Analog Devices Inc. Ensure the part number matches the exact quad-channel configuration. Check for any regional distribution restrictions or moisture sensitivity level requirements before ordering.

Selection Notes

Select this component when four isolated channels are required at 90 Mbps speeds. It is suitable for applications needing 2500 Vrms isolation without external transformers. Consider the 16-pin SOIC-W footprint for PCB layout constraints. Evaluate power consumption needs against the 11 mA nominal current draw.

Part Context

This part belongs to the ADuM140x family of quad-channel digital isolators. It shares architectural similarities with the ADUM1400 and ADUM1401 but offers specific channel directionality options. The series is designed for general-purpose isolation in noisy environments using proprietary silicon-on-insulator technology.

Replacement Considerations

Direct substitutes include other ADUM140x variants such as ADUM1400CRWZ-RL or ADUM1401CRWZ-RL, depending on required channel directionality. Verify pinout compatibility and electrical specifications match before substitution.
