ADUM140D0BRZ

Overview

The ADUM140D0BRZ is a general-purpose digital isolator from Analog Devices Inc., utilizing iCoupler technology. It features four isolated channels with a unidirectional input-to-output configuration (4:0). The device supports data rates up to 150Mbps and offers a common-mode transient immunity of 75kV/µs. It operates within a supply voltage range of 1.7V to 5.5V and provides 3000Vrms isolation voltage. Packaged in a 16-SOIC surface-mount format, it functions across an industrial temperature range of -40°C to 125°C.

Feature Summary

• Utilizes proprietary iCoupler magnetic coupling technology for robust signal isolation without external magnetics.
• Provides high common-mode transient immunity to maintain signal integrity in noisy environments.
• Supports wide operating supply voltages compatible with various logic families.

Applications

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

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm channel configuration and package variant. Ensure compatibility with system isolation voltage requirements and thermal management needs. Cross-reference datasheet revisions for any pinout or electrical parameter updates before finalizing procurement specifications.

Selection Notes

Select this component when unidirectional isolation is sufficient for the application design. Consider the 16-SOIC footprint constraints and the 150Mbps speed limit relative to system timing requirements. Evaluate the 3000Vrms isolation rating against regulatory standards applicable to the target end-use environment.

Part Context

This part belongs to the ADuM140 series of quad-channel digital isolators. It shares the core iCoupler architecture with variants like the ADUM140D1BRZ, differing primarily in internal channel mapping or configuration options defined by the manufacturer's ordering nomenclature.

Replacement Considerations

The ADUM140D1BRZ is a documented substitute within the same family. Verify functional equivalence regarding channel directionality and electrical characteristics before substitution.
