ADUM2400ARIZ-RL

Digital Isolators Overview

The ADUM2400ARIZ-RL is a quad-channel digital isolator from Analog Devices Inc., utilizing iCoupler magnetic coupling technology. It provides galvanic isolation with a rated voltage of 5000Vrms and supports bidirectional data transmission at speeds up to 90Mbps. The device features a common-mode transient immunity (CMTI) of 25kV/µs, ensuring reliable signal integrity in noisy environments. Operating on supply voltages between 2.7V and 5.5V, it offers propagation delays of 100ns maximum with rise/fall times of 3ns typical. Packaged in a 16-SOIC surface-mount format, it operates within a temperature range of -40°C to +105°C.

Digital Isolators Feature Summary

• Integrates four independent bidirectional channels for high-density signal isolation
• Employs on-chip transformer technology for robust galvanic isolation without external magnetics
• Delivers high common-mode transient immunity to maintain performance in electrically noisy systems

Digital Isolators Applications

• Industrial automation control systems requiring isolated communication interfaces
• Medical equipment needing safe patient isolation barriers
• Power electronics monitoring circuits for inverters and motor drives

Digital Isolators Procurement Notes

Verify the specific suffix RL indicates reel packaging when ordering. Confirm the 16-SOIC package dimension matches your PCB footprint requirements. Ensure supply voltage rails align with the 2.7V to 5.5V operational range. Check for RoHS compliance status if required by your manufacturing standards. Validate lead times as availability may vary by region.

Digital Isolators Selection Notes

Select this component when bidirectional data flow is required across an isolation barrier. Compare CMTI ratings against system noise levels to ensure signal integrity. Consider the 90Mbps data rate limit for bandwidth-sensitive applications. Evaluate power consumption against thermal constraints in enclosed enclosures. Verify compatibility with logic levels on both sides of the isolation boundary.
