ADUM1100BR

Overview

The ADUM1100BR is a single-channel digital isolator from Analog Devices, utilizing iCoupler technology to integrate high-speed CMOS with monolithic air core transformer technology. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 100 Mb/s. Key electrical specifications include an insulation voltage of 2500 Vrms, a propagation delay of 18 ns, and a typical rise/fall time of 3 ns. The device draws 800 uA of operating current and dissipates 240 mW of power. It functions in unidirectional mode with a pulse width of 10 ns and is rated for operation between -40 C and +125 C.

Feature Summary

• Integrates high-speed CMOS logic with monolithic air core transformer technology for signal isolation.
• Provides unidirectional data transmission capability suitable for general-purpose applications.
• Offers robust galvanic isolation performance without the limitations of traditional optical coupling.

Applications

• Isolation buffers for medical peripherals
• Industrial peripheral interface isolation
• USB cable isolator circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging variants (tube vs. reel) against official datasheets. Ensure the part number suffix matches required delivery formats. Cross-reference manufacturing dates and lifecycle status to avoid obsolete stock.

Selection Notes

Select this component when a single-channel, unidirectional digital isolator is required for systems needing 2500 Vrms isolation. It is appropriate for designs prioritizing low power consumption and small footprint over multi-channel integration. Verify that the 100 Mb/s data rate meets system timing requirements and that the SOIC-8 package fits the PCB layout constraints.
