ADUM1446ARQZ-RL7

Digital Isolators Overview

The ADUM1446ARQZ-RL7 is a micro-power, quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It operates within a supply voltage range of 2.25 V to 3.6 V and supports data rates up to 2 Mbps. The device provides 2500 Vrms isolation voltage and features a common mode transient immunity of 25 kV/µs. Propagation delay is specified at 80 ns typical. It is housed in a 16-lead QSOP package and functions bidirectionally across three input channels and one output channel.

Digital Isolators Feature Summary

• Micro-power operation for energy-efficient applications
• Bidirectional communication capability across four channels
• High common mode transient immunity for signal integrity

Digital Isolators Applications

• Industrial process control systems
• Medical equipment isolation interfaces
• Power metering circuits

Digital Isolators Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure correct packaging and electrical specifications. Confirm that the 16-lead QSOP package meets your PCB layout requirements. Cross-reference the part number with current product change notifications to identify any recent manufacturing updates or material changes that may affect compatibility.

Digital Isolators Selection Notes

Select this component when low power consumption and high-speed digital isolation are required in a compact form factor. The 2.25 V to 3.6 V operating range suits single-supply logic interfaces. Ensure the 2500 Vrms isolation rating aligns with safety standards for your specific application environment. Consider the 80 ns propagation delay for timing-sensitive designs.

Digital Isolators Part Context

This part belongs to the ADuM144x series of micro-power digital isolators from Analog Devices. The series leverages iCoupler technology to provide robust isolation without external magnetics. The -RL7 suffix specifically denotes tape and reel packaging for automated assembly processes, distinguishing it from tube-packaged variants like the ADUM1446ARQZ.

Digital Isolators Replacement Considerations

The ADUM1442ARQZ-RL7 serves as a functional substitute within the same series, offering identical channel count and isolation ratings. Verify pinout compatibility and specific current consumption differences before substitution.
