Hello folks! Recently, I'm trying to interface couple of mic to my microcontroller for finding out frequency of my speech. I built a microphone module and used OPA344 for amplification.
But, Currently when i checked the output; It look like a signal of +3 to -3V is coming out. Which is not accepted on microcontroller.
Any idea, how can i shift this signal in range of 0 to 5.5V amplitude range. I don't want to filter out any signal. (I guess, it would be a basic question)
Thanks everybody.
