MAX14930DAWE+

Digital Isolators Overview

The MAX14930DAWE+ is a four-channel digital isolator utilizing capacitive coupling technology, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.71V to 5.5V and supports data rates up to 1Mbps. The device provides 2750Vrms isolation voltage with a typical common-mode transient immunity (CMTI) of 25kV/µs. Propagation delays are specified at a maximum of 7.5ns for low-to-high transitions and 7.4ns for high-to-low transitions, with pulse width distortion capped at 4.5ns. Rise and fall times are typically 2ns each. It functions reliably across an operating temperature range of -40°C to +125°C and is housed in a 16-SOIC package with a 7.50mm width.

Digital Isolators Feature Summary

• Four unidirectional channels provide general-purpose digital isolation without integrated power supplies.
• Capacitive coupling technology ensures robust signal transmission across the isolation barrier.
• High common-mode transient immunity protects against noise in electrically noisy environments.
• Wide operating temperature range supports deployment in demanding industrial conditions.

Digital Isolators Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing reliable signal separation
• Power metering applications for accurate data acquisition

Digital Isolators Procurement Notes

Verify the specific suffix DAWE+ corresponds to the wide SOIC package variant when sourcing. Confirm that the required data rate aligns with the 1Mbps specification, as higher-speed variants exist within the same family. Ensure compatibility with the 1.71V to 5.5V supply voltage range for your target application logic levels. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Digital Isolators Selection Notes

Select this component when four isolated channels are required at moderate data speeds. The 1Mbps rate distinguishes it from faster 150Mbps counterparts like the MAX14930CASE+. Consider the 7.50mm SOIC package width for PCB layout constraints compared to narrower options. Verify that the 2750Vrms isolation rating meets safety certification requirements for your specific end-use environment.

Digital Isolators Part Context

This part belongs to the MAX1493x series of digital isolators, which offers various channel counts and speed grades. The MAX14930DAWE+ specifically targets applications needing four channels with lower bandwidth than the high-speed MAX14930CASE+. It shares the same core capacitive isolation architecture but differs in packaging and performance metrics compared to other members of the family.

Digital Isolators Replacement Considerations

Direct substitutes include other MAX14930 variants such as MAX14930CASE+ or MAX14930EAWE+, though these offer significantly higher data rates. Ensure any replacement maintains the 16-SOIC footprint and 2750Vrms isolation rating if those parameters are critical.
