MSP430 SD-16A

When SD-16A in unipolar input mode and the common mode voltage is zero,  Can be measured accurately at the level of mV DC voltage？
In other words, a pair of differential input to the ground, SD-16A conversion results in theory can be achieved, can it be used?
We need to deal with the models are relative to the  level mV DC small signal

    Alvin,
    If I'm understanding correctly, yes you should be able to take measurements in the mV range. Your measurement step size will depend on your reference voltage, given as VREF/2^16. Which is 18uV for a 1.2V Reference.

    If you have further questions, can you please tell me which MSP you are using?
