ADUM2280BRIZ-RL

Overview

The ADUM2280BRIZ-RL is a dual-channel digital isolator manufactured by Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.7 V to 5.5 V and supports data rates up to 100 Mb/s. The device features bidirectional channels with a typical propagation delay of 24 ns and rise/fall times of 3 ns. It provides 5000 Vrms isolation voltage and withstands a common-mode transient immunity of 25 kV/µs. Operating temperatures span from -40°C to +125°C, housed in a 16-SOIC package.

Feature Summary

• Integrates two independent bidirectional signal paths using proprietary iCoupler magnetic coupling technology for galvanic isolation.
• Provides high common-mode transient immunity rated at 25 kV/µs to maintain signal integrity in noisy environments.
• Supports data transmission speeds up to 100 Mb/s with low propagation delay characteristics.
• Operates reliably across an extended industrial temperature range from -40°C to +125°C.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing galvanic isolation for safety compliance
• Power electronics monitoring circuits with high-voltage noise environments

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when ordering. Confirm that the bidirectional channel configuration matches the design requirements, as unidirectional variants exist within the same family. Ensure ESD protection measures are implemented during handling due to moisture sensitivity classification. Cross-reference the latest datasheet revision for any updates on recommended soldering profiles or storage conditions prior to procurement.

Selection Notes

Select this component when bidirectional data flow is required between isolated domains. Compare against unidirectional models like the ADUM2200 if directionality constraints allow for smaller footprints or lower power consumption. Evaluate the 100 Mb/s speed requirement against slower, lower-power alternatives if bandwidth permits. Consider the 16-SOIC package dimensions for PCB layout compatibility and thermal management needs in dense assemblies.

Part Context

This part belongs to the ADuM228x series of dual-channel digital isolators from Analog Devices. It complements other devices in the portfolio such as the ADUM2281, which offers different channel configurations or speed options. The series leverages silicon dioxide insulation layers to provide robust isolation without the need for external transformer drivers.

Replacement Considerations

Direct substitutes include the ADUM2280ARIZ-RL for alternative binning or the ADUM2281BRIZ-RL if unidirectional channels suffice. Verify pinout compatibility before swapping with other dual-channel isolators from different manufacturers.
