The\noutput is rail-to-rail, so when the sound gets louder, the output goes up to\n5Vpp! You can set the gain from 25x to 125x. This is about 200mVpp (about 6\"\naway at normal speaker volume) for anything you would expect a \"line level\"\ninput without clipping, or down to about 1Vpp which is ideal for reading from\na microcontroller ADC. suitable for connecting to. how to use: Connect GND to\nground and VCC to 2.4~5VDC. The audio waveform is output from the OUT pin. The\noutput has a DC bias of VCC\/2, so when it's completely quiet the voltage will\nbe a steady VCC\/2 volts (DC coupled). If your audio equipment requires AC-\ncoupled audio, please connect a 100uF capacitor between the output pin and the\ninput terminal of your device. The 100uF cap is not required when connecting\nto an audio amplifier that includes differential inputs or decoupling\ncapacitors. The output pins are not designed to drive speakers or anything\nlike that, but the smallest headphones you can't put in your ears will work\nwith an audio amplifier (such as a 3.7W stereo amplifier) If you want to\nconnect the amplifier directly to the speakers. No amplifier or decoupling\ncapacitors are required when connecting to microcontroller pins. Connect the\nOUT pin directly to the microcontroller's ADC pin. For audio-reactive\nprojects, we recommend using an FFT driver library that takes audio input and\nconverts it to frequencies.
