MAX14930AAWE+T

Overview

The MAX14930AAWE+T is a general-purpose digital isolator manufactured by Analog Devices Inc./Maxim Integrated. It features four unidirectional channels with a data rate of 1Mbps and an isolation voltage of 2750Vrms. The device utilizes capacitive coupling technology and operates within a supply voltage range of 1.71V to 5.5V. It is housed in a 16-SOIC package (0.295 inch, 7.50mm width) and supports surface mount installation. The component functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for digital signal transmission using capacitive coupling technology.
• Supports high common-mode transient immunity for reliable operation in noisy environments.
• Offers flexible power supply compatibility with a wide input voltage range.

Applications

• Industrial automation systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics control circuits with high-voltage separation requirements

Procurement Notes

Verify the specific suffix AAWE+T against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the procurement source provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit components. Confirm that the 16-SOIC package dimensions match your PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when unidirectional signal isolation is required at lower data rates up to 1Mbps. It is suitable for applications where cost-effective isolation is prioritized over high-speed performance. Consider the 16-SOIC package size for board space constraints. Verify that the 2750Vrms isolation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the MAX1493x series of digital isolators from Maxim Integrated, now part of Analog Devices. The series includes variants with different channel configurations and data rates. The MAX14930 specifically focuses on four-channel unidirectional isolation. These devices are designed to replace traditional transformer and optocoupler solutions in modern electronic designs.

Replacement Considerations

MAX14930EAWE+T offers similar isolation but with higher data rates. MAX14934EAWE+T provides bidirectional capabilities. Check datasheets for exact parameter matching before substitution.
