ADUM1100ARZ

Overview

The ADUM1100ARZ is a single-channel digital isolator utilizing iCoupler technology, which integrates high-speed CMOS circuitry with monolithic air core transformer coils. It provides unidirectional signal isolation with a data rate of 100 Mb/s and an insulation voltage rating of 2500 Vrms. The device operates within a supply voltage range of 3 V to 5.5 V, drawing a typical quiescent current of 800 uA. Key electrical parameters include a propagation delay of 18 ns and rise/fall times of 3 ns. It supports general-purpose applications and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates monolithic air core transformer technology for magnetic coupling isolation
• Provides unidirectional signal transmission capability
• Supports high-speed data rates up to 100 Mb/s
• Operates on standard logic supply voltages

Applications

• General purpose digital isolation
• Industrial process control systems
• Medical equipment signal isolation
• Power management circuit interfaces

Procurement Notes

Verify the specific suffix (e.g., ARZ vs. ARZ-RL7) to confirm packaging type, as tube and reel variants exist. Confirm RoHS compliance status through official documentation. Check current availability as supply may be limited or restricted in certain regions. Ensure the SOIC-8 package matches your PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when unidirectional isolation is required for single-channel applications. Consider the 100 Mb/s data rate limit for signal speed requirements. Evaluate the 2500 Vrms insulation rating against system safety standards. Verify that the 3 V to 5.5 V operating range aligns with the target system power supply constraints.

Part Context

This part belongs to the ADuM1100 series of digital isolators manufactured by Analog Devices. It represents a solution based on iCoupler technology, distinguishing it from traditional optocouplers by using magnetic coupling instead of optical transmission. The series is designed for robust performance in noisy environments while maintaining low power consumption.

Replacement Considerations

Check for ADUM1100ARZ-RL7 if reel packaging is preferred over tubes. Verify compatibility with other single-channel isolators from the same family if pinout adjustments are acceptable.
