actually 16 bit 16bit two inputs from ADC to apply to get fft which are signed

When those values arrive are they uint16() or int16() ? Whatever they are when they arrive, should they be interpreted as int16() signed 16 bit values? What voltage value does the all-0 bit pattern correspond to? What voltage value does the all-1 bit pattern correspond to? What voltage value is associated with if the first bit is 0 and the remaining 15 bits are all-1 ?
