    I need amplifier circuit for piezoelectric transducer connected to arduino ADC.
    Does anyone have functional circuit and schematics with component values for that?
    I do NOT need any principle circuit.
    I use TDK's Piezo Haptic Actuator - PowerHap (Type 2.5G). It's capacitance is 0.8uF.
    Measured output signal in my application will be couple of mVs.
    Piezo is next to arduino (short and stable wires).
    Needed bandwidth is 0.1-10Hz.
    Do I need charger amp, voltage amp or both to get desired 0-5V signal for arduino?
    How to tackle signal drifting and decay?
