MAX9790AETJ+

Audio Amplifiers Overview

The MAX9790AETJ+ is a stereo Class AB audio amplifier manufactured by Analog Devices Inc./Maxim Integrated. It integrates DirectDrive headphone amplifiers and speaker drivers within a single 32-pin TQFN package. The device operates on a supply voltage range of 4.5V to 5.5V. It delivers 2W per channel into 4-ohm loads and 100mW per channel into 16-ohm loads. Key electrical characteristics include pop suppression, mute functionality, short-circuit protection, thermal shutdown, and shutdown modes.

Audio Amplifiers Feature Summary

• Integrates stereo Class AB speaker amplifiers with DirectDrive headphone outputs for simplified system design.
• Includes built-in pop suppression and mute controls to enhance user experience during power transitions.
• Provides comprehensive protection features including short-circuit protection, thermal shutdown, and shutdown mode.

Audio Amplifiers Applications

• Portable multimedia devices requiring integrated speaker and headphone driving capabilities
• Windows Vista-compliant audio systems
• Mobile phones and handheld gaming consoles

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required packaging format. Check current availability status as inventory levels fluctuate. Ensure compliance with RoHS directives if applicable to your region. Validate that the 32-TQFN footprint aligns with your PCB layout requirements before finalizing procurement.

Audio Amplifiers Selection Notes

Select this component when a single IC solution is needed for both stereo speakers and headphones. It is suitable for applications powered by 4.5V to 5.5V rails. Consider the 32-TQFN package size constraints. Evaluate if the Class AB topology meets efficiency requirements compared to Class D alternatives. Verify that the integrated protections suffice for the target environment.

Audio Amplifiers Part Context

This part belongs to the MAX9790 series of audio amplifiers from Maxim Integrated. It is designed to replace discrete solutions for speaker and headphone driving. The series focuses on reducing bill-of-materials count in portable electronics. It shares functional similarities with other DirectDrive products but offers specific output power ratings for stereo applications.

Audio Amplifiers Replacement Considerations

Direct substitutes may include other MAX9790 variants with different suffixes for packaging or temperature ranges. Cross-reference pinouts and electrical specifications carefully. No alternative part numbers are explicitly confirmed in the provided source material.
