ADUM4400CRWZ-RL

Overview

The ADUM4400CRWZ-RL is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 5000Vrms isolation voltage with a common-mode transient immunity of 25kV/µs. The device supports data rates up to 90Mbps and operates on a single supply voltage ranging from 2.7V to 5.5V. Key electrical parameters include a maximum propagation delay of 32ns and typical rise/fall times of 3ns. It functions within an operating temperature range of -40°C to +105°C and is housed in a 16-SOIC package.

Feature Summary

• Integrates four independent unidirectional signal channels for high-density isolation applications
• Employs iCoupler magnetic coupling technology to eliminate the need for external transformer drivers
• Provides enhanced electrostatic discharge (ESD) protection capabilities

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reinforced insulation barriers
• Power electronics control circuits

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure storage conditions meet specified humidity requirements to prevent package damage during soldering processes.

Selection Notes

Select this component when high-speed data transmission up to 90Mbps is required alongside robust 5000Vrms isolation. Consider the 16-SOIC footprint for space-constrained designs. Evaluate power consumption against system thermal constraints, noting the specific supply voltage range requirements for stable operation.

Part Context

This part belongs to the ADUM4400 series of general-purpose digital isolators. It represents a solution for replacing traditional optocouplers in modern electronic designs, offering superior performance metrics including higher bandwidth and better reliability over temperature variations compared to legacy technologies.

Replacement Considerations

Cross-reference with other ADUM4400 variants for packaging differences. Verify pin compatibility if substituting with similar channel-count isolators from different manufacturers.
