MAX14930EAWE+

Digital Isolators Overview

The MAX14930EAWE+ is a four-channel unidirectional digital isolator from Analog Devices, utilizing capacitive coupling technology. It operates within a supply voltage range of 1.71 V to 5.5 V on both sides and provides an insulation voltage of 2750 Vrms. The device supports data rates up to 25 Mb/s with a typical propagation delay of 21.1 ns. It features a common-mode transient immunity of 25 kV/µs and functions reliably across an industrial temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC-Wide (WSOIC) format, it consumes 27.2 mA of operating current.

Digital Isolators Feature Summary

• Four independent channels provide high-density signal isolation in a compact package.
• Capacitive coupling architecture ensures robust performance against electromagnetic interference.
• Dual independent power supplies allow flexible level shifting between different logic domains.

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment signal transmission
• Power metering and energy management circuits

Digital Isolators Procurement Notes

Verify the specific suffix EAWE+ to confirm the 25 Mbps data rate variant, as other suffixes indicate different speeds. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the WSOIC-16 footprint matches your PCB layout constraints. Check for availability restrictions or regional sales limitations directly with authorized distributors.

Digital Isolators Selection Notes

Select this component when four isolated bidirectional paths are not required, but unidirectional isolation at 25 Mbps is necessary. Compare against the MAX14930CAWE+ if higher speed up to 150 Mbps is needed, or the MAX14930AAWE+ for lower speed applications. Consider the thermal dissipation capabilities of the SOIC-Wide package under continuous operation conditions.

Digital Isolators Part Context

This part belongs to the MAX14930 series of general-purpose digital isolators. It shares the same physical footprint and basic functionality with variants offering different data rates, such as 1 Mbps or 150 Mbps. The series is designed to replace bulky magnetic isolators in modern electronic designs.

Digital Isolators Replacement Considerations

Direct functional substitutes include the MAX14930CAWE+ for higher speed requirements and the MAX14930AAWE+ for lower speed needs. Verify pin compatibility and electrical specifications before substitution.
