How do I connect this microphone to an ADC?
In circuit below you 've see how to power on a Mic, remove it's DC component through a capacitor, amplify it using an op-amp.

Value of resistors depend on your aplication. In most cases 1M resistor is replaced by a 10K-100K resistor.

Depending on your application you can filter it's output to remove undesired noises.
