ADUM3200ARZ-RL7

Overview

The ADUM3200ARZ-RL7 is a dual-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 1 Mb/s. The device provides 2500 Vrms isolation voltage and exhibits a common-mode transient immunity of 25 kV/µs. Key electrical parameters include a propagation delay of 150 ns, rise/fall times of 10 ns, and power consumption of 1 mA on the primary side and 1.3 mA on the secondary side. It functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrates two independent channels for bidirectional or unidirectional signal isolation using proprietary magnetic coupling architecture.
• Provides enhanced system-level ESD reliability with high common-mode transient immunity to prevent false triggering in noisy environments.
• Delivers low power consumption suitable for energy-efficient designs while maintaining signal integrity over long isolation distances.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors.
• Medical equipment interfaces needing certified isolation for patient safety compliance.
• Power electronics control circuits isolating gate drivers from high-voltage switching nodes.

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Check for any recent lifecycle notices regarding obsolescence or alternative recommendations directly from Analog Devices.

Selection Notes

Choose this component for applications demanding robust isolation with moderate data speeds. Compare against higher-speed variants if throughput exceeds 1 Mb/s. Consider thermal performance within the specified temperature range during layout. Validate that the 2500 Vrms rating meets the insulation requirements of your target application standard.

Part Context

This part belongs to the ADUM3200 series of dual-channel digital isolators. It shares the same core isolation technology as other members but differs in speed and polarity configurations. The series is designed to replace traditional optocouplers in many industrial and communication interfaces.
