MAX14930AAWE+

Overview

The MAX14930AAWE+ is a four-channel digital isolator from Analog Devices/Maxim Integrated, housed in a 16-pin SOIC-Wide package. It provides 2750 Vrms isolation voltage with capacitive coupling technology. The device supports a maximum data rate of 1 Mbps and features unidirectional signal transmission across all four channels. Operating supply voltage ranges from 1.71 V to 5.5 V, with typical operating currents of 5 mA and 27.2 mA. Propagation delay is specified at 38.6 ns, and it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides galvanic isolation for four independent digital signal channels using capacitive coupling technology.
• Supports unidirectional data transmission with high common-mode transient immunity.
• Operates over an extended industrial temperature range suitable for harsh environments.

Applications

• Industrial automation systems requiring isolated digital communication
• Medical equipment needing safe patient isolation
• Power electronics control circuits

Procurement Notes

Verify the specific suffix 'AAWE+' against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure compatibility with system voltage levels and isolation requirements before procurement. Check current availability status as distribution may vary by region.

Selection Notes

Select this component when four isolated digital channels are required with moderate data rates up to 1 Mbps. Consider the 16-pin SOIC-Wide package for PCB layout constraints. Verify that the 2750 Vrms isolation rating meets safety standards for the intended application environment.

Part Context

This part belongs to the MAX14930 series of general-purpose digital isolators. It is designed to replace optocouplers in many applications, offering smaller size, lower power consumption, and better performance consistency. The series includes variants with different channel configurations and data rates.

Replacement Considerations

Check for direct substitutes like the MAX14930EAWE+ which offers higher data rates (25 Mbps) but maintains similar isolation and package specifications. Ensure functional equivalence regarding channel count and directionality when selecting alternatives.
