I have this component http://docs-europe.electrocomponents.com/webdocs/0f2a/0900766b80f2a57c.pdf. It is not clear to me what type of circuit I need to use to amplify the signal from this microphone and then convert it using an ADC.
I have a few of them, I measured their resistance using my multimeter, they show a resistance of about 1k ohm. On the underside of the microphone there seems to be some sort of SMD component (either resistor or capacitor) that bridges the metal part of the two terminals of the microphone. What purpose could this serve?
