What distinguishes this\naudio amplifier from others is that it features volume control (i.e. gain),\nDynamic Range Compression (DRC), Automatic Gain Control (AGC), enable\/disable\namplifier, and its ability to be configured through software via I2C. Its\nefficient class-D operation also means low heat and long battery life when\ndriving 4Ω speakers at up to 2.8W in stereo, and 8Ω speakers at up to 1.7W in\nstereo. This is quite a bit more power than the mono amplifier (TPA2005D1) or\nNoisy Cricket stereo amplifier (LM4853). It won't shake a stadium but it will\nprovide plenty of volume for your audio projects. The DRC and AGC is unique\ncompared to other audio amplifiers. This is a powerful feature that allows you\nto \"even out\" the loud and quiet sections from your audio input. It also\nallows you to maximize the volume of your speakers. By fine-tuning the\nsettings, you can get the most volume to prevent distortion of the audio\nsignal. Using the DRC, AGC, and\/or the limiter alone allows you to protect\nyour speakers from getting damaged by extremely loud playback. We've written\nan extensive Library that allows you to easily control all of the amplifier's\nfeatures from simple gain control to advanced AGC. Note that you will need to\nsend the configuration to the TPA2016D2 upon every power cycle. The board has\nbeen designed to be user friendly! Screw terminals are provided for the audio\ninput, power, shutdown, and speaker output. A 3.5mm TRS connector is included\nas an alternative to easily insert an audio cable. Utilizing our handy Qwiic\nsystem, no soldering is required to connect it to the rest of your system when\nconfiguring the amplifier's settings. A power LED (PWR) is included on the\nboard to indicate when power is applied to the amplifier through VIN. It can\nbe disabled by cutting the LED jumper on the bottom side.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eThe SparkFun Qwiic Speaker Amp includes the Texas Instruments TPA2016D2 class-D stereo audio amp.\u003c\/li\u003e\n         \u003cli\u003eFeatures: Filter-free Class-D Architecture, Flexible Operation with\/without I2C, Programmable Dynamic Range Compression (DRC) Parameters.\u003c\/li\u003e\n         \u003cli\u003eAlso Features: Programmable Automatic Gain Control (AGC) Parameters, Programmable Volume Control, Selectable Gain from 28dB to 30dB in 1-dB Steps (When Compression is Used) Selectable Attack, Release, and Hold Times, 4 Selectable Compression Ratios.\u003c\/li\u003e\n         \u003cli\u003eThe DRC and AGC is unique compared to other audio amplifiers.
