ADUM3100ARZ-RL7

Overview

The ADUM3100ARZ-RL7 is a single-channel digital isolator utilizing iCoupler technology. It provides 2500Vrms isolation voltage and supports data rates up to 25Mbps. The device features a common-mode transient immunity of 25kV/µs and operates within a supply voltage range of 2.7V to 5.5V. It is housed in an 8-pin SOIC package with a width of 3.90mm.

Feature Summary

• Implements isolation using proprietary iCoupler chip-scale transformer technology
• Provides enhanced system-level electrostatic discharge reliability
• Delivers high common-mode transient immunity for noisy environments

Applications

• Industrial process control systems requiring signal isolation
• Medical equipment needing galvanic isolation for safety compliance
• Power management circuits involving isolated communication interfaces

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm the ARZ designation corresponds to the lead-free RoHS-compliant variant. Ensure the 8-SOIC package dimensions match the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring a single isolated channel with high-speed data transmission capabilities. Consider the 25Mbps rate against system timing constraints. Evaluate the 2500Vrms isolation rating against the specific circuit voltage requirements to ensure adequate safety margins.

Part Context

This part belongs to the ADuM3100 series of digital isolators from Analog Devices. The series leverages silicon dioxide-based insulation barriers to replace traditional magnetic or optical isolation methods, offering smaller form factors and lower power consumption compared to legacy solutions.

Replacement Considerations

Check for direct pin-compatible alternatives within the ADuM3100 family that may offer different speed grades or isolation ratings. Verify that any substitute maintains the same 8-SOIC package and electrical characteristics.
