ADUM7640CRQZ-RL7

Overview

The ADUM7640CRQZ-RL7 is a six-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 1000 Vrms isolation voltage with a common-mode transient immunity of 15 kV/µs. The device supports data rates up to 25 Mb/s and operates within a supply voltage range of 3 V to 5.5 V. Typical propagation delay is 14 ns, with rise and fall times of 2.8 ns. It functions in temperatures from -40°C to +105°C and is housed in a 20-QSOP package.

Feature Summary

• Six independent bidirectional signal channels integrated into a single component
• High common-mode transient immunity for reliable operation in noisy environments
• Compact surface-mount packaging reduces board space requirements

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment signal interfaces
• Power electronics gate drive circuits

Procurement Notes

Verify the specific suffix RL7 corresponds to reel packaging when sourcing. Confirm availability status as distribution channels may report limited stock or discontinuation. Ensure the QSOP-20 footprint matches the target PCB design before procurement.

Selection Notes

Select this component for applications requiring high channel density and robust noise immunity. Compare against other iCoupler variants based on required isolation voltage ratings and specific channel configurations. Verify power consumption limits align with system thermal constraints.

Part Context

This part belongs to the ADUM7640 series of general-purpose digital isolators. It shares the iCoupler architecture with related models like the ADUM7641, differing primarily in internal channel configuration. The series is designed for replacing traditional optocouplers in modern interface designs.

Replacement Considerations

Direct substitutes include the ADUM7641CRQZ-RL7 for similar isolation specifications. Verify pin compatibility and channel directionality when cross-referencing with other ADUM76xx family members.
