ADUM3482ARSZ-RL7

Overview

The ADUM3482ARSZ-RL7 is a quad-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides 3750 Vrms isolation voltage and supports unidirectional data transmission at speeds up to 1 Mbps. The device operates within a supply voltage range of 3 V to 5.5 V and features a typical propagation delay of 90 ns. It is housed in a 20-SSOP package and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrates four independent digital channels for signal isolation using proprietary magnetic coupling technology.
• Provides robust electrical isolation with a rated insulation voltage of 3750 Vrms.
• Supports high-speed data communication with a maximum data rate of 1 Mbps.
• Ensures reliable operation in harsh environments with extended industrial temperature ratings.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing safety-certified signal separation
• Power electronics control circuits
• Instrumentation interfaces

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm availability status as distribution listings may indicate limited stock or discontinuation. Ensure compatibility with SSOP-20 footprints during procurement planning. Check RoHS compliance documentation for regulatory adherence.

Selection Notes

Select this component for applications requiring four isolated channels with unidirectional data flow. Compare against ADUM3480 variants if bidirectional communication is necessary. Consider power consumption differences between ARSZ and BRSZ series versions. Validate that the 1 Mbps speed meets system timing requirements.

Part Context

This part belongs to the ADuM348x family of small, quad-channel digital isolators. It shares the same physical footprint and basic functionality with other variants like the ADUM3480 and ADUM3481, differing primarily in channel directionality and data rate specifications. The family utilizes Analog Devices' iCoupler technology for compact isolation solutions.

Replacement Considerations

ADUM3480ARSZ-RL7 offers similar isolation but supports bidirectional channels. ADUM3482BRSZ-RL7 provides higher data rates up to 25 Mbps. Verify pinout compatibility and electrical parameters before substituting any alternative part numbers.
