ADUM140E1BRQZ-RL7

Overview

The ADUM140E1BRQZ-RL7 is a quad-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mbps and an isolation voltage of 3000 Vrms. The device operates within a supply voltage range of 1.7 V to 5.5 V and offers a common-mode transient immunity (CMTI) of 75 kV/µs. Packaged in a 16-pin SSOP, it supports a wide operating temperature range from -40°C to 125°C.

Feature Summary

• Integrates high-speed CMOS logic with single-chip air-core transformer technology for robust signal isolation.
• Provides bidirectional data transmission capability across four independent isolated channels.
• Delivers high common-mode transient immunity to ensure reliable operation in noisy environments.

Applications

• Industrial automation systems requiring galvanic isolation between control and power stages.
• Medical equipment needing safe patient isolation interfaces.
• Power metering applications involving high-voltage sensing circuits.

Procurement Notes

Verify the specific suffix 'QZ' against official Analog Devices documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the component matches the required 16-SSOP footprint for PCB layout compatibility before finalizing procurement orders.

Selection Notes

Select this component when four isolated digital channels are required within a compact surface-mount package. Consider the 150 Mbps data rate and 75 kV/µs CMTI for high-speed industrial communication links. Evaluate the 1.7 V to 5.5 V supply range compatibility with existing system logic levels. Verify thermal performance requirements against the specified -40°C to 125°C operating range.

Part Context

This part belongs to the ADuM140E family of digital isolators based on iCoupler technology. It serves as a direct replacement for traditional optocouplers in applications demanding higher speed and lower power consumption. The series integrates passive components on-chip to reduce external bill of materials.

Replacement Considerations

Check for ADUM140E1BRZ variants which may share identical electrical characteristics but differ in packaging or reel configuration. Verify pinout compatibility if substituting with other quad-channel isolators from different manufacturers.
