Working Principle

The TPA3111D1QPWPRQ1 is a low-power Class-D audio amplifier. In simple terms, this device uses a switching technique to deliver power-efficient audio power to the load. This technique works by switching an audio signal between two power supply rails at very high speeds, and it results in a significantly higher efficiency when compared to traditional linear amplifiers.

The device is capable of delivering up to 18Wx2 of audio power from a 4.5V to 28V power supply, with over 98% efficiency. It also features a 24V integrated gate driver and enables a rich audio power delivery, with a minimum of external components.

The working principle of the TPA3111D1QPWPRQ1 is as follows: the audio signal is firstly conditioned and amplified by an internal amplifier, then it is compared with a triangle waveforms to generate switching signals. These switching signals drive the MOSFETs and control the power flow to the speaker. This process has a lower power requirement, allowing the device to deliver high audio power with low distortion, while maintaining high efficiency.
