ADUM4402CRWZ-RL

Overview

The ADUM4402CRWZ-RL is a quad-channel digital isolator from Analog Devices, featuring magnetic coupling technology for signal isolation. 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 insulation voltage of 5000 Vrms and includes enhanced ESD protection capabilities. Propagation delay is specified at 32 ns, with typical rise and fall times of 3 ns. It functions reliably across an operating temperature range of -40°C to +105°C and is housed in a SOIC-16 surface-mount package.

Feature Summary

• Integrates four independent unidirectional channels for high-density signal isolation.
• Incorporates on-chip magnetic coupling technology to ensure robust galvanic isolation.
• Features enhanced electrostatic discharge (ESD) protection for improved system reliability.
• Supports high-speed data transmission with low propagation delay characteristics.

Applications

• Industrial automation control systems requiring isolated communication interfaces.
• Medical equipment needing high-voltage isolation for patient safety compliance.
• Power electronics applications involving gate drive signals and feedback loops.
• Data acquisition systems utilizing isolated analog-to-digital converter interfaces.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required reel packaging format. Check current availability status as supply constraints may affect immediate fulfillment. Ensure the ordering part number aligns precisely with the requested electrical specifications and package type to avoid integration errors during procurement.

Selection Notes

Select this component when high channel density and elevated insulation voltage are critical requirements. The integrated DC/DC converter is absent; external power management is necessary for isolated side supplies. Evaluate thermal performance within the SOIC-16 footprint against application heat dissipation needs. Consider the 90 Mb/s data rate capability relative to system timing constraints and noise immunity requirements.

Part Context

This part belongs to the ADUM4402 series of quad-channel digital isolators. It shares the SOIC-16 package form factor with other devices in the ADUM family but differs in channel count and speed specifications. The product line emphasizes magnetic coupling isolation techniques over capacitive alternatives, offering distinct trade-offs in common-mode transient immunity and power consumption profiles.
