ADUM140D1BRZ-RL7

Overview

The ADUM140D1BRZ-RL7 is a quad-channel digital isolator 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 supply voltages from 1.8 V to 5 V, drawing 12 mA per side. Key electrical parameters include a propagation delay of 15 ns, rise/fall times of 2.5 ns, and an isolation voltage of 3000 Vrms. It functions within a temperature range of -40°C to +125°C and is housed in a 16-SOIC package.

Feature Summary

• Quad-channel unidirectional signal isolation using proprietary iCoupler magnetic coupling technology
• High-speed performance with 150 Mb/s data rate and low propagation delay
• Robust noise immunity characterized by 75 kV/µs common-mode transient rejection
• Wide operating supply voltage range supporting 1.8 V to 5 V logic interfaces

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment signal conditioning and isolation barriers
• Power management circuits for isolated communication interfaces
• Automotive electronics involving sensor data transmission

Procurement Notes

Verify the specific suffix BRZ-RL7 against official Analog Devices documentation to confirm reel packaging and tape specifications. Ensure compatibility with RoHS3 standards and check moisture sensitivity level (MSL 3) requirements for storage and handling. Confirm that the 16-SOIC footprint matches the target PCB design constraints before procurement.

Selection Notes

Select this component when high-density quad-channel isolation is required in a small surface-mount package. The unidirectional configuration suits applications where signal flow is strictly one-way. Consider the 150 Mb/s speed limit and 3000 Vrms isolation rating against system requirements. Evaluate power consumption at 12 mA per side relative to thermal constraints in the final assembly.

Part Context

This part belongs to the ADuM140 series of digital isolators from Analog Devices. It represents a family of devices leveraging iCoupler technology to replace traditional optocouplers. The series offers various channel configurations and directionality options, providing designers with scalable isolation solutions for diverse interface needs.

Replacement Considerations

Cross-reference with other ADuM140 variants such as ADUM140E1BRZ-RL7 for similar specifications. Verify pinout compatibility and electrical parameter equivalence before substitution. Consult official Analog Devices replacement guides to ensure functional parity in the target application.
