There is some information in this document illustrating different circuits, amongst other things, dealing with piezo sensors.
Thanks I will read it. However I think I’m getting squeeky clean signals other than the idle voltage problem which is probably a limitation of the teensy reference voltage.
I will test it when I get the voltage reference IC’s in a few days.
I will post a picture of the waveforms I’m getting when I get home.
