I am using a Electret Microphone MAX 4466 and have wired it to a bandpass filter that will only allow frequencies from 10KHz to 20KHz to pass through. I then want to convert the signal to a digital signal that the arduino can read and will then light up an LED.Any suggestions on what ADC I need and how to set this up?

I am trying to detect the sound metal makes...
So you don't need an A/D.
Just an envelope follower and threshold detector behind that bandpass filter.
Then straight into a digital pin.
That shouldn't be a problem for any Arduino.
