ADUM2280BRIZ

Overview

The ADUM2280BRIZ is a dual-channel digital isolator from Analog Devices, utilizing proprietary iCoupler magnetic coupling technology. It provides bidirectional data transmission with a data rate of 100 Mb/s and an isolation voltage of 5000 Vrms. The device operates within a supply voltage range of 2.7 V to 5.5 V, drawing an operating supply current of 800 uA. Key electrical parameters include a propagation delay time of 24 ns, typical rise and fall times of 3 ns, and a pulse width of 10 ns. It is housed in a 16-pin SOIC-W package and supports a wide operating temperature range from -40°C to +125°C.

Procurement Notes

Verify the specific suffix (BRIZ) against the official Analog Devices datasheet to ensure correct packaging and temperature grade. Confirm availability status as distribution channels may report limited stock or discontinuation. Ensure the procurement source is authorized to guarantee component authenticity and traceability.

Selection Notes

Select this component when bidirectional data transfer is required at speeds up to 100 Mb/s. The 16-pin SOIC-W package offers a compact footprint for space-constrained designs. Consider the 800 uA supply current for battery-operated applications where power efficiency is critical alongside high isolation voltage requirements.

Part Context

This part belongs to the ADUM228x series of dual-channel digital isolators. It shares architectural similarities with the ADUM2281 and ADUM2282 but differs in output polarity configuration. The series leverages silicon dioxide insulation layers on CMOS chips to achieve high performance and small form factors compared to traditional transformer-based isolators.

Replacement Considerations

Check the ADUM2281BRIZ and ADUM2282BRIZ for functional equivalents with different default output states. Verify pin compatibility and logic polarity before substitution. Consult the manufacturer's cross-reference guide for any newer generations within the iCoupler family.
