SparkFun Qwiic Speaker Amp

The SparkFun Qwiic Speaker Amp includes the Texas Instruments TPA2016D2 stereo, filter-free class-D audio power amplifier. What distinguishes this audio amplifier from others is that it features volume control (i.e. gain), Dynamic Range Compression (DRC), Automatic Gain Control (AGC), enable/disable amplifier, and its ability to be configured through software via I2C. Its efficient class-D operation also means low heat and long battery life when driving 4Ω speakers at up to 2.8W in stereo, and 8Ω speakers at up to 1.7W in stereo.

DEV-20690-003

The DRC and AGC is unique compared to other audio amplifiers. This is a powerful feature that allows you to "even out" the loud and quiet sections from your audio input. It also allows you to maximize the volume of your speakers. By fine-tuning the settings, you can get the most volume to prevent distortion of the audio signal. Using the DRC, AGC, and/or the limiter alone allows you to protect your speakers from getting damaged by extremely loud playback. SparkFun have written an extensive Arduino Library that allows you to easily control all of the amplifier's features from simple gain control to advanced AGC. Note that you will need to send the configuration to the TPA2016D2 upon every power cycle.
