ADUM221N1BRWZ-RL

Overview

The ADUM221N1BRWZ-RL is a dual-channel digital isolator from Analog Devices Inc., utilizing iCoupler® magnetic coupling technology. It provides 5000Vrms isolation voltage and supports data rates up to 150Mbps with a common-mode transient immunity of 75kV/µs. The device features two unidirectional channels and one reverse channel, housed in a 16-SOIC package. It operates within a supply voltage range of 3V to 5.5V and functions across temperatures from -40°C to 105°C.

Feature Summary

• High-speed bidirectional communication capability via integrated reverse channel
• Robust 5.0 kVrms isolation rating for enhanced safety
• Exceptional common-mode transient immunity for noisy environments

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage isolation barriers
• Power metering applications with ground potential differences

Procurement Notes

Verify the specific suffix 'N1' against official Analog Devices documentation to confirm the inclusion of the reverse channel feature. Ensure the 16-SOIC package dimensions match your PCB footprint requirements. Confirm that the 5000Vrms isolation rating meets your system's safety standards before finalizing procurement.

Selection Notes

Select this component when high-speed data transmission (up to 150Mbps) is required alongside robust isolation. The integrated reverse channel simplifies design by eliminating external components for feedback signals. Consider the 16-SOIC package size and operating temperature range relative to your application constraints.

Part Context

This part belongs to the ADuM221N series of digital isolators based on iCoupler technology. It offers a compact solution for replacing traditional optocouplers in space-constrained designs while providing superior performance in speed and reliability.

Replacement Considerations

Check Analog Devices datasheets for direct pin-compatible alternatives within the ADuM220N or ADuM225N series if different channel configurations are needed.
