MAX98928EWX+T

Audio Amplifiers Overview

The MAX98928EWX+T is an 8V boosted Class D speaker amplifier with integrated IV sense technology, manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.0 V to 5.5 V and supports stereo audio amplification. The device utilizes a WLP-36 package for compact integration. It features built-in protection mechanisms including thermal shutdown and short-circuit protection. The component is designed for high-efficiency audio output in portable applications.

Audio Amplifiers Feature Summary

• Integrated IV sense capability for real-time speaker impedance monitoring and protection
• Boosted Class D architecture enabling efficient audio amplification from low-voltage supplies
• Built-in thermal and short-circuit protection for enhanced system reliability

Audio Amplifiers Applications

• Portable media players and smartphones requiring high-efficiency audio output
• Tablets and handheld devices needing compact amplifier solutions
• Automotive infotainment systems utilizing IV sense for speaker diagnostics

Audio Amplifiers Procurement Notes

Verify the exact suffix 'EWX+T' against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through current datasheets. Check for obsolescence notices as availability may be limited. Ensure compatibility with your PCB footprint for the WLP-36 package. Validate supply chain sources for authenticity.

Audio Amplifiers Selection Notes

Select this component when IV sense functionality is required for speaker protection and diagnostics. Consider the WLP-36 package constraints for board space limitations. Evaluate power supply requirements to ensure stable operation within the specified voltage range. Compare efficiency metrics against alternative Class D amplifiers if battery life is critical. Verify interface compatibility with host processors.

Audio Amplifiers Part Context

Part of the MAX9892 series, which includes related models like the MAX98927. This series focuses on boosted Class D amplifiers with advanced protection features. The MAX98928 specifically adds IV sense capabilities not present in all family members. It complements other Maxim audio ICs in complete audio subsystem designs.

Audio Amplifiers Replacement Considerations

The MAX98927EWX+T is a similar model but lacks IV sense functionality. Verify if IV sense is mandatory for your application before substituting. Both share the same package and basic Class D architecture. Cross-reference pinouts and control interfaces to ensure compatibility.
