ADUM3480ARSZ-RL7

Overview

The ADUM3480ARSZ-RL7 is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It features bidirectional signal transmission with a data rate of 25 Mb/s and an insulation voltage of 3750 Vrms. The device operates on a single 5.5 V supply, drawing 600 uA of quiescent current. Key electrical parameters include a propagation delay of 33 ns, rise/fall times of 3 ns, and a pulse width distortion of 1000 ns. It functions within a temperature range of -40°C to +125°C and is housed in a 20-SSOP package.

Feature Summary

• Integrates four independent bidirectional channels for high-density signal isolation
• Employs iCoupler magnetic coupling technology for robust galvanic isolation
• Supports high-speed data transmission up to 25 Mb/s per channel
• Provides high common-mode transient immunity for reliable operation in noisy environments

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing patient isolation barriers
• Power metering applications with high-voltage separation requirements
• Inverter control circuits for motor drives

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required reel packaging configuration. Check for recent production change notices that may affect pinout or electrical specifications. Ensure storage conditions comply with moisture sensitivity level requirements prior to reflow soldering.

Selection Notes

Select this component when four isolated bidirectional channels are required within a compact footprint. Compare against unidirectional alternatives if directionality constraints exist. Evaluate power consumption requirements against the 600 uA quiescent current specification. Ensure the 3750 Vrms isolation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the ADuM348x series of small, quad-channel digital isolators. It shares the same core iCoupler architecture as other variants in the family but differs in channel directionality and specific electrical characteristics. The RL7 suffix indicates tape and reel packaging suitable for automated surface-mount assembly processes.
