ADUM4402CRIZ-RL

Overview

The ADUM4402CRIZ-RL is a quad-channel digital isolator from Analog Devices, utilizing magnetic coupling technology for signal transmission. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 90 Mb/s. The device provides an isolation voltage of 5000 Vrms with a typical propagation delay of 32 ns. It features unidirectional channels and operates reliably across a temperature range of -40°C to +105°C. Packaged in a SOIC-16 surface-mount format, it draws 830 uA of operating current.

Feature Summary

• Provides four independent digital isolation channels using capacitive-free magnetic coupling technology
• Supports high-speed data transmission with a maximum rate of 90 Mb/s
• Ensures robust electrical safety with 5000 Vrms isolation voltage rating
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage isolation barriers
• Power metering circuits for energy monitoring
• Inverter drives and motor control applications

Procurement Notes

Verify the complete part number including the suffix to ensure correct packaging configuration. Confirm RoHS compliance status through official manufacturer documentation before integration. Check for moisture sensitivity level requirements during storage and handling procedures. Ensure compatibility with existing PCB footprint specifications for the SOIC-16 package.

Selection Notes

Select this component when multiple isolated digital channels are required in a compact form factor. Consider the 5000 Vrms rating for applications demanding high dielectric strength between circuit domains. Evaluate the 90 Mb/s data rate against system timing requirements. Verify that the unidirectional signal flow aligns with the specific communication protocol being implemented.

Part Context

This component belongs to the ADuM440x series of quad-channel digital isolators manufactured by Analog Devices. It shares architectural similarities with the ADUM4401 but may differ in specific channel configurations or pinouts. The series utilizes proprietary iCoupler technology to replace traditional optocouplers in many designs.
