ADUM3472WARSZ

Overview

The ADUM3472WARSZ is a four-channel digital isolator from Analog Devices, utilizing iCoupler technology for magnetic signal coupling. It integrates an internal transformer driver and a dc-to-dc converter to provide isolated power. The device offers 2500 Vrms insulation rating and supports data rates up to 1 Mbps with a common mode transient immunity of 25 kV/µs. It operates within a temperature range of -40°C to +105°C and is housed in a 20-lead SSOP package.

Feature Summary

• Integrates a dc-to-dc converter to supply isolated power, eliminating the need for external isolated supplies.
• Provides bidirectional communication across four independent channels using proprietary magnetic coupling technology.
• Features high common mode transient immunity to maintain signal integrity in noisy environments.

Applications

• Industrial automation systems requiring galvanic isolation between control and power stages.
• Medical equipment needing reliable signal transmission across safety barriers.
• Power metering applications involving high voltage isolation requirements.

Procurement Notes

Verify the specific suffix (ARSZ) against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compatibility with system voltage levels and thermal management requirements before finalizing procurement orders.

Selection Notes

Select this component when integrated isolated power and multi-channel digital isolation are required in a single package. Consider the 1 Mbps data rate limit and 2500 Vrms isolation barrier when designing circuits that demand high-speed or higher voltage isolation than other family members.

Part Context

This part belongs to the ADUM347x series of digital isolators. It shares the core iCoupler architecture with variants like the ADUM3471 and ADUM3473 but differs in channel count and specific integration features such as the internal power converter configuration.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADUM347x family. Verify if the ADUM3472WCRSZ-RL7 meets packaging needs if reel format is preferred over tube.
