MAX22820EAWA+T

Digital Isolators Overview

The MAX22820EAWA+T is a dual-channel digital isolator manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with a single 3.3 V supply and provides bidirectional data transmission via an SPI-compatible interface. The device offers 5000 Vrms isolation voltage and a common-mode transient immunity of 200 kV/µs. It supports data rates up to 10 Mbps in both directions. Packaged in an 8-SOIC surface-mount format, it ensures signal integrity across isolated boundaries.

Digital Isolators Feature Summary

• Provides galvanic isolation between high-voltage and low-voltage domains
• Supports bidirectional data transmission for SPI interfaces
• Features high common-mode transient immunity for noise rejection

Digital Isolators Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power metering and energy monitoring

Digital Isolators Procurement Notes

Verify the exact datasheet revision and RoHS compliance status directly with Analog Devices or authorized distributors before procurement. Confirm that the SOIC-8 package dimensions match your PCB footprint requirements. Ensure that the operating voltage range aligns with your system's 3.3 V logic levels. Check for any specific handling precautions related to electrostatic discharge during assembly.

Digital Isolators Selection Notes

Select this component when bidirectional communication is required across an isolation barrier. It is suitable for applications needing moderate data rates up to 10 Mbps. Consider its 5000 Vrms rating for safety-critical environments. Evaluate the 200 kV/µs CMTI for noisy industrial settings. Compare against single-channel alternatives if only one isolated path is needed.

Digital Isolators Part Context

This part belongs to the MAX22820 family of digital isolators designed for robust signal transmission. It complements other Maxim Integrated isolation products by offering integrated SPI compatibility. The series focuses on providing reliable performance in compact packages for modern electronic designs requiring electrical separation.

Digital Isolators Replacement Considerations

MAX22820EAWA+ is the non-tape reel variant of the same component. Verify pinout compatibility if substituting with other dual-channel isolators from different manufacturers.
