Hi All, I've purchased this https://www.adafruit.com/products/2716 mic breakout from Adafruit the other day and it works great, I get somewhat weak signal, let's say if you talk directly into mic the amplitude on analogRead values only about 50-ish, but it is okay for my learning curve so I'm happy. In their description they mentioned that this mic is pretty much can be connected directly to analog pin and they only added 3v regulator to it.
So, in my attempt to understand how this whole thing work I have ordered the same particular microphone , here its datasheet: http://www.knowles.com/index.php/eng/content/download/5642/89383/version/7/file/SPW2430HR5H-B.pdf
And I am going to connect it to Arduino myself from scratch, it is going to be Pro Mini 3.3v version or arduino with voltage regulator infront of arduino so I do not really need to add voltage regulator to the microphone itself, right? I am curious: can I indeed just directly connect this mic to digital input pin and read its values? Is all I need is to just need to send 3.3v from arduino to mic's Vdd pin and read voltage off Vout pin? No need to install any resistors to limit current or anything like that? I understand that there are two capacitors involved as shown in datasheet, but why I was concerned about current is because in "electric specs" table it says that mic's input current is about 100uA, so I am concerned if I am going to burn it by sending 3.3v to it from arduino without any other current limiting device?
Where is the catch? Or no catch?
