Description: The SparkFun Qwiic Speaker Amp includes the Texas Instruments TPA2016D2 stereo, filter-free class-D audio power amplifier. 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.
