I am a beginner in arduino, and electronics in general.
FOUR SINGLE-ENDED OR TWO DIFFERENTIAL INPUTS
I am using other dynamic pressure sensors with Labview and specialized DAQ that can go up to 500Khz.
still have to amplify the 100mv max signal from the transducer, and if I want to use the SdFat code which is an ANALOGbin logger, this means I cant use the ADS 1115, right?
2) So do I have to do my own non inverting amplifier circuit using the TL 072 or TL082? Then log the amplified analog data using SdFat code?
I came accross this instructable where a 40Khz audio signal of 200mv was amplified using TL082, and then read by the arduino through bypassing analogread() and writing a special code. Your thoughts on that approach is appreciated.http://www.instructables.com/id/Arduino-Audio-Input/
