In the typical application circuit diagram in figure 4 of MAX4063 datasheet, why are there two 2.2 uF capacitors connected from two ends of microphone to ground?
The 2.2uF capacitor and series resistor forms a low pass filter to provide the microphone with a clean bias voltage. If there is interference on the bias voltage, it will generate noise at the MAX4063 output. Therefore, the capacitor can serve as a filter to give microphone a "clean" signal to be amplified by MAX4063.
The circuit diagram is included below for convenience.
