ADUM7641CRQZ-RL7

Overview

The ADUM7641CRQZ-RL7 is a six-channel digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It provides bidirectional signal isolation with a rated insulation voltage of 1000 Vrms and a common-mode transient immunity of 15 kV/µs. The device operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 25 Mb/s. It features low propagation delay of 14 ns and operates across an extended temperature range from -40°C to +105°C. Packaged in a 20-pin QSOP, it integrates multiple channels for space-efficient designs.

Feature Summary

• Bidirectional signal isolation capability
• Multi-voltage domain interface support
• High common-mode transient immunity

Applications

• Industrial automation systems
• Medical equipment isolation
• Power metering applications

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm availability status as distribution may vary by region. Ensure compatibility with QSOP-20 footprint requirements during procurement planning.

Selection Notes

Select this component for designs requiring six isolated channels in a compact surface-mount package. Consider the 1000 Vrms insulation rating for safety-critical interfaces. Evaluate power consumption against system constraints given the specified operating currents.

Part Context

This part belongs to the ADUM764x series of general-purpose digital isolators. It shares architectural similarities with other iCoupler devices but offers a specific six-channel configuration. The QSOP-20 package distinguishes it from wider or narrower channel variants in the family.

Replacement Considerations

Check ADUM7641CRQZ for tube-packaged equivalents. Verify pinout compatibility before substituting with other six-channel isolators.
