ADUM140D0BRQZ-RL7

Overview

The ADUM140D0BRQZ-RL7 is a quad-channel digital isolator utilizing iCoupler magnetic coupling technology. It provides 3000Vrms isolation with a data rate of 150Mbps and 75kV/µs common-mode transient immunity. The device features four unidirectional channels in a 16-SSOP package, operating on a 1.7V to 5.5V supply with a maximum propagation delay of 15ns.

Feature Summary

• Robust quad-channel isolation architecture
• High-speed data transmission capability
• Enhanced common-mode transient immunity

Applications

• Industrial communication interfaces
• Medical equipment signal isolation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when ordering. Confirm the SSOP-16 package width matches design constraints. Check RoHS compliance status for regulatory requirements. Ensure input disable functionality aligns with system logic needs.

Selection Notes

Select this component for applications requiring high CMTI and moderate speed. Compare against ADUM1402 series for lower speed options. Consider ADUM140E series for higher insulation ratings. Verify voltage levels match the target interface standards.

Part Context

Part of the ADuM140D family of robust digital isolators. Designed for general-purpose isolation in noisy environments. Utilizes proprietary iCoupler technology for compact integration.

Replacement Considerations

ADUM140D0BRQZ is the non-reel variant. ADUM1402BRWZ offers lower speed but wider availability. ADUM140E1BRZ provides higher insulation voltage.
