Special Features
【Description】The MAX4466 is a micropower operational amplifier optimized for use as a microphone preamplifier.
【Feature】Combination of optimized gain bandwidth products and supply current, as well as low voltage operation in an ultra-small package.
【Usage】Connect GND to ground, VCC to 2.4 - 5VDC. The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2, so when it's quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio device requires AC-coupled audio, please place a 100uF capacitor between the output pin and the input of the device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required.
【Notice】The output pin is not designed to drive speakers, but to drive the smallest in-ear headphones. You need an audio amplifier (such as a 3.7W stereo amplifier). If you want to connect the amplifier directly to the speakers or it is connected to a microcontroller pin, no amplifier or decoupling capacitor is needed to connect the OUT pin directly to the microcontroller ADC pin. For audio-reactive projects, it is recommended to use the FFT driver library, which can take audio input and 'translate' it into frequencies.
