The MAX4466 is a micropower operational amplifier optimized for use as a microphone preamp. Use is simple: connect GND to ground, VCC with 2.4-5VDC. For the best performance, use the "quietest" power supply available (for an Arduino this would be the 3.3V power supply). Widely used in mobile phones, digital repeaters, headphones, hearing aids, microphone preamps, portable computers and voice recognition systems. Continuously adjustable gain: the gain can be adjusted from 25x to 125x via a potentiometer Attention: when powered by 5V voltage, remember to dissipate heat when the current is high
