ADUM1100BR-RL7

Overview

The ADUM1100BR-RL7 is a single-channel digital isolator utilizing iCoupler technology, which integrates high-speed CMOS circuitry with monolithic air-core transformer coupling. It provides electrical isolation for unidirectional data transmission at speeds up to 100 Mb/s. The device operates within a supply voltage range of 3 V to 5.5 V and draws a typical quiescent current of 800 µA. It features a propagation delay of 18 ns and supports pulse widths down to 10 ns. The component offers an insulation voltage rating of 2500 Vrms and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Integrates monolithic air-core transformer technology for magnetic coupling isolation
• Supports unidirectional signal transmission with general-purpose protocol compatibility
• Provides high common-mode transient immunity via integrated isolation barrier

Applications

• Industrial automation control systems requiring galvanic isolation
• Medical equipment signal interfacing where safety isolation is mandated
• Power electronics gate drive circuits for switching protection
• Isolated communication interfaces in noisy electromagnetic environments

Procurement Notes

Verify the specific suffix and RoHS compliance status directly with Analog Devices or authorized distributors, as availability may vary by region. Confirm that the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the operating temperature range meets your environmental specifications before finalizing procurement decisions.

Selection Notes

Select this component when a single-channel, low-power solution is required for isolating digital signals between different ground domains. It is suitable for applications needing moderate data rates up to 100 Mbps without the complexity of multi-channel devices. Consider the unidirectional nature of the channel when designing the signal flow architecture.
