ADUM4402BRIZ

Overview

The ADUM4402BRIZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 5000 Vrms isolation voltage and supports data rates up to 90 Mb/s with a typical propagation delay of 32 ns. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, drawing 830 uA of quiescent current. It features unidirectional signal transmission and is housed in a 16-SOIC package. The component ensures high common-mode transient immunity of 25 kV/µs and functions within an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates four independent channels for simultaneous signal isolation using proprietary magnetic coupling technology.
• Provides robust electrical isolation rated at 5000 Vrms to protect low-voltage circuits from high-voltage transients.
• Delivers high-speed data transmission capabilities suitable for demanding communication interfaces.
• Ensures signal integrity through high common-mode transient immunity characteristics.

Applications

• Industrial automation systems requiring isolated communication links
• Medical equipment needing patient isolation barriers
• Power metering applications involving galvanic isolation
• Inverter and motor control circuits

Procurement Notes

Verify the specific suffix RL against official documentation to confirm reel packaging requirements. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the SOIC-16 footprint matches the design layout. Check for any recent product change notices that may affect specifications or availability.

Selection Notes

Select this component when four isolated channels are required within a compact surface-mount package. Consider the 90 Mb/s data rate limit for high-speed interface compatibility. Evaluate the 5000 Vrms isolation rating against system safety standards. Compare power consumption figures if battery-operated constraints exist.

Part Context

This part belongs to the ADUM4402 series of digital isolators. It shares the same core architecture as the ADUM4401 but offers higher data rate performance. The BRIZ suffix indicates a specific tape-and-reel packaging option within the standard SOIC-16 form factor. It is designed to replace legacy optocouplers in modern designs.

Replacement Considerations

The ADUM4401BRIZ serves as a functional substitute with lower data rate specifications. Verify pinout compatibility and isolation voltage ratings before substitution. Ensure the replacement meets the required thermal and electrical performance criteria for the specific application environment.
