BulletPoint1 : Amplification - Experience paralleled amplification with the 4466 op amp, designed specifically for enhancing sound clarity. Its al power ply no rejection ensures that you en and crisp sound output. Compared to other mic amp s, this module vers erior quality without the wanted no or distortion, making your projects sound incredible.
BulletPoint2 : Gain - Tailor your experience with a gain setting that rom 25x to 25x, providing the of amplification for your controller ADC projects. This ibility ows you to adapt to various sound s, ensu imal performance whether you're recording cate sou or amplifying robust s.
BulletPoint3 : Rail-to-Rail Output - The 4466 boasts a rail-to-rail output that can up to 5Vpp, accommodating sound sign without distortion. This feature guarantees that you will not a , as it enables vibr sound reproduction. For best results, it’s recommended to use a quiet power ply, izing the over quality of your applications.
BulletPoint4 : Simple Connections - Using the amplifier module couldn't be easier; simply connect GND to ound and V to a power source of 2.4 to 5V DC. The output pin is egically designed for easy tion with other devices, making it versatile for various applications, om controllers to sensors, without any hassle.
BulletPoint5 : DC Coupled Output - En the advantage of a steady VCC/2 volts at the output when the is quiet, thanks to its DC coupling. This ensures performance in applications, providing the essary voltage and stability. If AC coupling is needed, simply rt a 00uF acitor between the output pin and your device for seaml tion.

ProductDescription : 1. For amplification, we use the , an op amp designed to accomplish this delicate task.
2. With excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried.
3. You can set the gain from 25x to 125x, for reading from a microcontroller ADC. The output is rail‑to‑rail so if the sounds gets loudly, the output can go up to 5Vpp.
4. For the best performance, use the quietest supply available. The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your devices. If you are connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF is not required.
5. Using it is simple: connect GND to ground, VCC to 2.4-5VDC.
6. The output pin is not designed to drive speakers or anything but the smallest headphones, you'll need an audio amplifier (such as our 3.7W stereo amp) if you want to connect the amp directly to speakers.
