Texas Instruments Smart Amplifier Overview

Our smart amplifiers build upon the Class-D audio amplifier by adding the ability to real-time monitor the temperature and excursion of the speaker. Typical amplifiers do not have this capability and revert to attenuating the audio signal to ensure reliability. Smart Amps use the real-time temperature and excursion data to update the speaker model in real-time. This feedback allows the device to monitor the health of the speaker and optimize the sound quality to enable great audio.
