The Microphone AMP Board features a microphone connected to a power amplifier LM4864 designed for use in low-voltage consumer applications. The gain is internally set to 20 in order to keep external part count low, but the addition of a potentiometer and capacitor between pins 1 and 8 will increase the gain up to 200.
