Maxim MAX4466 is a opamp amplifier which by noise rejection and with some amplification is able to deliver clear and good quality sound. Using the following code, I'm noticing significant noise spikes on the output, as shown in the graph below. The amplifier has excellent power supply noise rejection, so this amplifier sound is clear and isn't nearly as noisy or scratchy as other mic amp breakouts. However, the systems I’ve purchased and assembled, such as the MAX4466, the op-amp design here, and a circuit very similar to this one, found here. In addition these amplifiers feature rail-to-rail outputs, high A VOL, plus excellent power-supply rejection and common-mode rejection ratios for operation in noisy environments. sch Author: christopher.
