    If an other Input is higher than 3.3V or lower than 0V you will have noise and error.
    So i use rail to rail opamps with the same supply as avcc.

    If your Impedance is more than 10k you need a capacitor at your input.
    If this become too slow, you need the opamp.

    It is not recomendet to use the internal diodes because the current in this diodes will disturbe the multiplexer so that OTHER INPUTS will produse false results! We use 6002 opamp with 3v3 supply.

    The Opamp with +/-12V Supply can kill the 3v3 Input of your teensy.

    So i use a railtorail opamp with 3v3/0V Supply for the analoginputs.

    I think, very_ high_speed and 16 bit resolution is not recomendet together.
    14 bit result is very good with buffer and filter and oversampling.
