ADUM4400BRIZ

Overview

The ADUM4400BRIZ is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 5000 Vrms isolation voltage with an 8mm creepage distance and supports data rates up to 10 Mb/s. The device features unidirectional channels in a 16-lead SOIC package, operating within a supply voltage range of 2.7 V to 5.5 V. It exhibits a propagation delay of 32 ns and common-mode transient immunity of 25 kV/µs, functioning reliably across temperatures from -40°C to +105°C.

Feature Summary

• Integrates four independent signal paths using on-chip coil technology for robust magnetic coupling isolation.
• Provides high common-mode transient immunity to maintain signal integrity in electrically noisy environments.
• Supports bidirectional logic transmission with low power consumption characteristics suitable for energy-efficient designs.

Applications

• Industrial automation systems requiring galvanic isolation between control and power stages
• Medical equipment needing certified isolation barriers for patient safety compliance
• Power metering applications involving high-voltage sensing and data acquisition

Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm RoHS compliance and moisture sensitivity level before storage. Ensure proper handling procedures are followed to prevent electrostatic discharge damage during assembly. Cross-reference datasheet revisions to confirm current specifications match design requirements.

Selection Notes

Select this component when four isolated channels are required within a single package footprint. Consider the 16-SOIC package dimensions for PCB layout constraints. Evaluate the 10 Mbps data rate against system timing requirements. Assess the 5000 Vrms isolation rating against circuit voltage potentials.
