MAX9713ETJ+

Audio Amplifiers Overview

The MAX9713ETJ+ is a mono Class D audio power amplifier in a 32-pin TQFN package. It operates from a single 10V to 25V supply and delivers up to 6W into an 8Ω load with greater than 85% efficiency. The device features a filterless architecture, eliminating the need for bulky output filters. Key electrical parameters include a quiescent current of 18mA, shutdown current of 0.2µA, and a power-supply rejection ratio of 76dB at 1kHz. Total harmonic distortion plus noise is specified at 0.07%, with a signal-to-noise ratio exceeding 95dB.

Audio Amplifiers Feature Summary

• Filterless Class D architecture eliminates the need for external output filters.
• Spread-spectrum mode reduces EMI-radiated emissions compared to conventional methods.
• Differential inputs minimize common-mode noise interference.
• Integrated click-and-pop suppression prevents audible transients during startup and shutdown.

Audio Amplifiers Applications

• LCD monitors
• LCD TVs
• Desktop PCs
• High-end notebook audio systems

Audio Amplifiers Procurement Notes

Verify that the component matches the specific MAX9713 mono configuration rather than the stereo MAX9714 variant. Confirm the presence of the exposed paddle (EP) on the 32-pin TQFN package for proper thermal grounding. Ensure the ordering suffix indicates lead-free construction as per standard specifications.

Audio Amplifiers Selection Notes

Select this component for applications requiring high-efficiency audio amplification without the board space penalty of traditional LC filters. The differential input architecture is suitable for noisy digital environments like desktop PCs. Consider the spread-spectrum feature if strict EMI compliance is required without additional shielding.

Audio Amplifiers Part Context

This part belongs to the MAX9713/MAX9714 family of 6W filterless Class D amplifiers manufactured by Maxim Integrated. The MAX9713 provides a mono channel configuration, while the MAX9714 offers stereo capability. Both share identical modulation schemes and protection features but differ in channel count and package dimensions.

Audio Amplifiers Replacement Considerations

The MAX9714ETJ+ is a compatible alternative for designs requiring stereo channels instead of mono output. Other filterless Class D amplifiers may be considered if different power levels or package sizes are required, though pin compatibility will vary.
