ADUM3472CRSZ-RL7

Overview

The ADUM3472CRSZ-RL7 is a four-channel digital isolator from Analog Devices, featuring an integrated transformer driver for magnetic coupling isolation. It operates within a supply voltage range of 3 V to 5.5 V and supports bidirectional data transmission at speeds up to 25 Mb/s. The device provides 2500 Vrms insulation voltage and exhibits a propagation delay of 60 ns. It is housed in an SSOP-20 package and functions reliably across an industrial temperature range of -40°C to +105°C.

Feature Summary

• Integrates a high-speed transformer driver to enable efficient magnetic coupling isolation without external components.
• Provides bidirectional signal transmission across four independent channels for versatile interface applications.
• Ensures robust electrical isolation with a rated insulation voltage of 2500 Vrms for safety-critical systems.

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment interfaces needing certified isolation barriers
• Power electronics gate drive circuits

Procurement Notes

Verify the specific suffix RL7 against official Analog Devices documentation to confirm reel packaging specifications. Confirm RoHS compliance status through current datasheets as regulatory requirements may evolve. Ensure the SSOP-20 footprint matches your PCB design constraints before finalizing procurement decisions.

Selection Notes

Select this component when four isolated channels are required with integrated driver capabilities. Compare pulse width distortion specifications against system timing requirements. Evaluate thermal performance within the SSOP-20 package relative to ambient operating conditions.

Part Context

This part belongs to the ADUM347x series of digital isolators, which utilize capacitive or magnetic coupling technologies. The ADUM3472 variant specifically offers four channels with internal transformer drivers, distinguishing it from variants that may require external drivers or offer different channel counts.

Replacement Considerations

Check ADUM3470ARSZ-RL7 and ADUM3473ARSZ-RL7 for potential pin-compatible alternatives within the same family. Verify functional equivalence regarding pulse width specifications and isolation ratings before substitution.
