Smart Sense Audio Amplifier 


  • The TFA9911 is a high efficiency class-D audio amplifier with a sophisticated speaker boost and protection algorithm. It can deliver 7.2 W peak output power into an 8Ohm speaker at a supply voltage of 3.6 V. The internal boost converter raises the supply voltage to 9.5 V, providing ample headroom for major improvements in sound quality. 

    With the new speaker-as-microphone solution, the TFA9911 will offer great audio recording quality and reducing wind-noise when talking. It also has tap sensing on the speaker which allows you to tap anywhere on the phone to take selfie or any other feather.
