ADUM7441ARQZ-RL7

Overview

The ADUM7441ARQZ-RL7 is a quad-channel digital isolator utilizing iCoupler technology. It provides 1000 Vrms isolation voltage with a data rate of 1 Mbps and propagation delay of 75 ns. Operating on a single supply from 3 V to 5.5 V, it features bidirectional channels in a QSOP-16 package. The device operates between -40°C and +105°C with typical rise/fall times of 2.8 ns.

Feature Summary

• Four independent bidirectional signal paths for high-density isolation
• Monolithic air-core transformer technology for magnetic coupling
• High common-mode transient immunity of 15 kV/µs
• Single-supply operation compatible with standard logic levels

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing patient isolation barriers
• Power management circuits with isolated gate drive signals
• Data acquisition systems with noisy ground environments

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the QSOP-16 footprint matches your PCB layout constraints. Ensure the 1000 Vrms isolation rating meets your safety standards requirements. Check current availability as distribution status may vary by region.

Selection Notes

Select this component when four isolated channels are required within a compact surface-mount package. Compare against ADUM7440 if channel directionality differs. Verify that the 1 Mbps speed suffices for your application timing. Consider thermal performance within the QSOP-16 enclosure for your design.

Part Context

This part belongs to the ADuM744x family of quad-channel digital isolators. It shares the iCoupler architecture with similar Analog Devices isolation products. The series offers various pinout configurations for different isolation needs. It serves as a solid-state alternative to traditional optocouplers.

Replacement Considerations

The ADUM7440ARQZ-RL7 is a confirmed substitute within the same family. Both share identical pinouts and core specifications. Verify channel directionality differences between these variants before substitution.
