MAX14931DAWE+

Digital Isolators Overview

The MAX14931DAWE+ is a general-purpose digital isolator featuring four channels in a 3/1 configuration. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 2750Vrms. The device supports data rates up to 1Mbps and offers a typical common-mode transient immunity (CMTI) of 25kV/µs. Operating on supply voltages between 1.71V and 5.5V, it ensures signal integrity across isolated domains. The component is housed in a 16-SOIC package with a 7.50mm width, designed for surface-mount installation.

Digital Isolators Feature Summary

• Provides galvanic isolation via capacitive coupling technology
• Supports unidirectional data transmission in a 3-input, 1-output channel configuration
• Features high common-mode transient immunity for noisy environments
• Operates within a wide industrial temperature range

Digital Isolators Applications

• Industrial automation systems requiring signal isolation
• Programmable logic controllers (PLCs)
• Inverters and motor control applications
• Power metering equipment

Digital Isolators Procurement Notes

Verify the specific suffix 'DAWE+' against official Analog Devices documentation to confirm the 16-SOIC package and 3/1 channel configuration. Ensure compatibility with system voltage requirements ranging from 1.71V to 5.5V. Confirm that the 2750Vrms isolation rating meets safety certification standards for the intended application environment.

Digital Isolators Selection Notes

Select this component when a 3/1 directional isolation topology is required rather than symmetric 2/2 or 4/0 configurations. Consider the 1Mbps data rate limit for high-speed applications where faster alternatives like the MAX14931CAWE+ might be necessary. Evaluate the 16-SOIC footprint constraints against available board space.

Digital Isolators Part Context

This part belongs to the MAX1493x family of digital isolators, which are designed to replace traditional magnetic couplers. The family includes variants with different channel configurations and data rates, such as the MAX14930 and MAX14932, allowing designers to optimize for cost, speed, and pin count based on specific interface requirements.

Digital Isolators Replacement Considerations

The MAX14931CAWE+ serves as a higher-speed alternative within the same package family. Designers should verify if the increased data rate capability is required and ensure that any pin-compatible substitutes maintain the same 3/1 channel configuration and isolation voltage ratings.
