ADUM3210BRZ-RL7

Overview

The ADUM3210BRZ-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 10 Mb/s. The device provides 2500 Vrms isolation voltage and features a common mode transient immunity of 25 kV/µs. Typical propagation delay is 50 ns, with rise and fall times of 3 ns. It functions in unidirectional mode across an operating temperature range of -40°C to +105°C. Power consumption is specified at 2 mA and 3.5 mA for the respective channels.

Feature Summary

• Integrates high-speed CMOS circuitry with single-chip transformer technology for robust signal isolation.
• Provides enhanced system-level ESD reliability compared to traditional optocoupler alternatives.
• Delivers independent isolation channels with high common-mode transient immunity.

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power metering applications with high-voltage interfaces

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the BRZ designation corresponds to lead-free RoHS compliance. Ensure the SOIC-8 package width matches your PCB footprint requirements. Cross-reference the datasheet revision date to confirm parameter accuracy against current manufacturing standards.

Selection Notes

Select this component when bidirectional isolation is not required, as it is strictly unidirectional. Compare power consumption figures against other iCoupler variants if low standby current is critical. Verify that the 10 Mb/s data rate meets your application's timing constraints. Ensure the 2500 Vrms isolation rating satisfies your safety regulatory requirements.

Part Context

This part belongs to the ADuM3210 series, which also includes the ADuM3211 variant. Both utilize Analog Devices' proprietary iCoupler technology. The series is designed to replace optocouplers in various interface applications. The ADuM3210 specifically offers two independent channels for unidirectional data transmission.

Replacement Considerations

The ADUM3211WBRZ is a related part number within the same family. Verify channel directionality and pinout compatibility before substitution. Check if the alternative package type fits your existing board layout without modification.
