ADUM141D0BRWZ

Digital Isolators Overview

The ADUM141D0BRWZ is a robust quad digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four independent channels with a 3:1 input-to-output configuration (three forward, one reverse). The device supports data rates up to 150 Mb/s and offers an insulation voltage of 3750 Vrms. It operates on a supply voltage range of 1.7 V to 5 V, with a typical operating current of 11.4 mA. Key performance metrics include a propagation delay of 15 ns, fall time of 2.5 ns, and a common-mode transient immunity of 75 kV/µs. It is housed in a 16-lead SOIC package.

Digital Isolators Feature Summary

• Integrates four isolated channels using proprietary iCoupler magnetic coupling technology for signal transmission without optical components.
• Provides high common-mode transient immunity to protect against fast-changing noise voltages across the isolation barrier.
• Supports unidirectional data flow with a flexible channel configuration, typically three inputs to one output.
• Operates within a wide industrial temperature range and accepts a broad supply voltage spectrum.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and sensors.
• Medical equipment needing reliable signal isolation for patient safety compliance.
• Power electronics interfaces for monitoring and control in inverters or motor drives.
• Communication gateways isolating different ground potentials in network infrastructure.

Digital Isolators Procurement Notes

Verify the specific suffix and packaging type when ordering, as availability may vary by region. Confirm that the 3750 Vrms insulation rating meets your system's safety requirements. Check for RoHS compliance status if environmental regulations apply to your deployment. Ensure the SOIC-16 footprint matches your PCB design constraints before finalizing procurement.

Digital Isolators Selection Notes

Choose this component when high channel density and robust isolation are required in a compact surface-mount package. It is suitable for designs needing moderate data speeds up to 150 Mbps with low power consumption. Consider the 3:1 channel split if most signals flow in one direction. Verify that the 1.7 V minimum supply voltage aligns with your logic levels.

Digital Isolators Part Context

This part belongs to the ADuM141 series of quad digital isolators from Analog Devices. It represents the industry-standard solution for replacing traditional optocouplers in space-constrained applications. The series is known for its small form factor and consistent performance across varying temperatures and supply conditions.

Digital Isolators Replacement Considerations

Direct substitutes include other parts within the ADuM141 family, such as the ADUM141D0BRZ or ADUM141E0BRZ, depending on the required insulation voltage level (3000 Vrms vs 3750 Vrms) and automotive qualification needs. Always verify pin compatibility and electrical specifications before swapping.
