    Perhaps you are correct. jonr suggested 'differential mode'. V0 would be the base of both inputs.
    I was unaware that the Teensy could perform a differential ADC measurements.
    The ADC in my Nano(s)...

    It is a DC voltage (source from a battery for what it is worth via a shunt regulator).
    The DC voltage and/or resistor values might need to be adjusted....

    Teensy ADC resolution

    I note that:
    1) the specifications for the Teeny 3.2 state it has a ADC resolution of 16 bits in hardware and useable resolution on 13 bits
    2) the specifications for the Teeny LC state it has a...
