MAX14931DAWE+T

Digital Isolators Overview

The MAX14931DAWE+T 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 2750 Vrms. The device supports data rates up to 1 Mbps and offers a typical common-mode transient immunity (CMTI) of 25 kV/µs. Operating on a supply voltage range of 1.71 V to 5.5 V, it ensures signal integrity across isolated boundaries. The component is housed in a 16-SOIC package and functions reliably within an operating temperature range of -40°C to +125°C.

Digital Isolators Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology for high reliability.
• Features a 3/1 channel configuration allowing flexible input-output mapping for complex interface requirements.
• Delivers high common-mode transient immunity to maintain signal integrity in noisy environments.

Digital Isolators Applications

• Industrial communication interfaces requiring robust signal isolation
• Medical equipment needing safe patient isolation barriers
• Power electronics control systems with high-voltage noise rejection

Digital Isolators Procurement Notes

Verify the specific suffix 'EAWE' or 'DAWE' against official Analog Devices documentation to confirm pinout and functional compatibility. Ensure the order matches the required data rate specifications, as variants exist within the MAX14931 family. Confirm RoHS compliance status directly from the manufacturer's latest certification documents before finalizing procurement.

Digital Isolators Selection Notes

Select this component when a 3/1 channel configuration is required for asymmetric data transmission paths. Consider the 1 Mbps data rate limit and 2750 Vrms isolation rating against system requirements. Evaluate the 16-SOIC package dimensions for PCB layout constraints. Compare CMTI performance against other isolators if high-speed transient noise immunity is critical for the application environment.
