ADUM140E1BRZ

Overview

The ADUM140E1BRZ is a general-purpose digital isolator from Analog Devices, utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a data rate of 150 Mbps and a common-mode transient immunity of 75 kV/µs. The device operates on a supply voltage range of 1.7 V to 5.5 V, drawing 12 mA of operating current. It provides 3000 Vrms isolation voltage and exhibits a propagation delay of 13 ns maximum. The component is housed in a 16-SOIC package and supports an 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 transmission.
• Provides galvanic isolation without requiring isolated power supplies or external transformers.
• Offers high common-mode transient immunity to maintain signal integrity in noisy environments.

Applications

• Industrial automation systems requiring reliable digital communication across isolation barriers.
• Medical equipment needing safe patient isolation and noise rejection.
• Power electronics control circuits interfacing low-voltage logic with high-voltage power stages.

Procurement Notes

Verify the specific suffix (e.g., BRZ) against official Analog Devices documentation to confirm pinout and packaging details. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the source is an authorized distributor to guarantee authenticity and traceability.

Selection Notes

Select this component when four independent unidirectional channels are required within a single package. Consider the 150 Mbps speed limit and 3000 Vrms isolation rating against system requirements. Evaluate the 16-SOIC footprint constraints and thermal dissipation capabilities for the target application environment.

Part Context

This part belongs to the ADuM140E series, which leverages iCoupler technology to replace traditional optocouplers. The series offers improved performance in terms of speed, power consumption, and reliability while maintaining small form factors suitable for dense PCB layouts.

Replacement Considerations

Check for direct substitutes within the ADuM140 family or other iCoupler-based quad-channel isolators from Analog Devices. Verify compatibility regarding channel count, isolation voltage, and package dimensions before substitution.
