ADUM140D1BRQZ-RL7

Overview

The ADUM140D1BRQZ-RL7 is a robust quad digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mb/s and a common-mode transient immunity of 75 kV/µs. The device operates on a single supply voltage ranging from 1.7 V to 5.5 V and provides 3000 Vrms isolation. Packaged in a 16-pin QSOP, it supports a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Utilizes iCoupler magnetic coupling technology for high-speed signal transmission without external magnetics
• Provides robust isolation with 3000 Vrms rating and 75 kV/µs common-mode transient immunity
• Features four unidirectional channels optimized for low propagation delay and pulse width distortion

Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix 'D1' against the official datasheet to confirm channel configuration and pinout compatibility. Ensure the QSOP-16 package dimensions match the target PCB footprint. Confirm RoHS compliance status through the manufacturer's current documentation before finalizing procurement specifications.

Selection Notes

Select this component when high-speed unidirectional isolation is required within a compact surface-mount package. The 150 Mb/s data rate suits applications demanding faster communication than standard 10 Mbps isolators. Consider the 1.7 V to 5.5 V supply range for flexibility in low-voltage logic interfaces.

Part Context

This part belongs to the ADUM140 series of digital isolators, which are designed to replace traditional optocouplers. The series offers superior performance in terms of speed, power consumption, and reliability. The 'D1' designation typically indicates a specific channel configuration within the quad isolator family.

Replacement Considerations

Check for direct replacements such as the ADUM140D1BRWZ or other variants within the ADUM140 family that may offer different packaging options like SOIC while maintaining identical electrical characteristics.
