ADUM140E0BRQZ-RL7

Overview

The ADUM140E0BRQZ-RL7 is a general-purpose digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It features four unidirectional channels with a 4:0 input-to-output configuration. 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-SSOP (0.154 inch width) housing, it functions across an industrial temperature range of -40°C to +125°C.

Feature Summary

• Employs proprietary iCoupler magnetic coupling technology for robust signal isolation without optical components.
• Provides high common-mode transient immunity to maintain signal integrity in noisy environments.
• Supports high-speed data transmission with low propagation delay characteristics.

Applications

• Industrial automation systems requiring galvanic isolation between microcontrollers and peripherals.
• Medical equipment needing reliable signal separation for patient safety compliance.
• Power electronics interfaces for monitoring and control circuits in high-voltage environments.

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the SSOP-16 package dimensions match your PCB footprint requirements. Ensure compatibility with the 1.7V to 5.5V supply voltage range for your target application logic levels. Check for RoHS3 compliance status if required by your manufacturing standards.

Selection Notes

Select this component when unidirectional data flow is sufficient for the isolation barrier. The 4-channel configuration suits applications connecting multiple digital lines simultaneously. Consider the 150Mbps speed limit against your system's clock requirements. The wide operating temperature range makes it suitable for harsh industrial settings.

Part Context

This part belongs to the ADUM140 series of digital isolators from Analog Devices. It shares the core iCoupler architecture with other variants in the family but differs in channel count, directionality, and packaging options. The E0BRQZ designation specifies the quad unidirectional configuration in the SSOP package.

Replacement Considerations

Cross-reference with ADUM140D0BRQZ or ADUM140E1BRZ for similar isolation specifications. Verify pinout compatibility before substitution as package variations may exist. Ensure the replacement part meets the same 3000Vrms isolation rating and 150Mbps data rate requirements.
