ADUM7640CRQZ

Overview

The ADUM7640CRQZ is a six-channel digital isolator utilizing iCoupler technology, offering 1 kVrms isolation voltage and 25 Mbps data rate. It features bidirectional signal transmission with a propagation delay of 14 ns and common-mode transient immunity of 15 kV/µs. Operating on a 3 V to 5.5 V supply, it draws 11 mA or 44 mA depending on channel configuration. The device operates from -40°C to +105°C in a 20-lead QSOP package.

Feature Summary

• Six-channel magnetic coupling architecture for high-density signal isolation
• Bidirectional data transmission capability across all channels
• High common-mode transient immunity for noisy environments

Applications

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

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm the 20-lead QSOP footprint matches your PCB layout requirements. Ensure the bidirectional channel configuration aligns with your circuit design needs before procurement.

Selection Notes

Select this component for applications requiring six isolated channels in a compact surface-mount package. Compare against unidirectional variants if directionality constraints exist. Verify thermal performance within the specified operating temperature range for your enclosure design.

Part Context

This part belongs to the ADUM764x series of iCoupler digital isolators. It shares the same core technology and pinout compatibility as other members in the family, differing primarily in channel count and directionality configurations such as the four-channel ADUM7641.

Replacement Considerations

The ADUM7641CRQZ serves as a related variant within the same series. Note that the ADUM7641 offers four channels instead of six, which may affect board space utilization and channel availability for your specific application.
