Operation

In both SINGLE-ENDED and DIFFERENTIAL modes, the effective output of the ADC is

an 11-bit, signed, two’s complement digital value. In DIFFERENTIAL Mode, the ADC

can output values across the entire 11-bit range, from –1024 to +1023. In SINGLE-

ENDED Mode, the output generally ranges from 0 to +1023, but offset errors can cause

small negative values.
