That's not what I am getting at. If your sensor's analog output value has less than 0.097656 % (1/1024 * 100%) noise, then, yes, you need a more accurate ADC. Otherwise there is no point. sincerely, Marije _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/mailman/listinfo/linux-audio-user
