ous conversions at 10sps or single conversions at the
40sps setting (effectively 10sps due to four sample
sigma-delta settling), the ADC has 16-bit noise-free res-
olution. The noise-free resolution drops to 10 bits at the
maximum sampling rate of 512sps. Differential inputs
support unipolar (between 0 and VREF) and bipolar
(between ±VREF) modes of operation. Note: Avoid
combinations of input signal and PGA gains that
exceed the reference range at the ADC input. The
ADOU bit in the status register indicates if the ADC has
over-ranged or under-ranged.
Zero-scale and full-scale calibrations remove offset and
gain errors. Direct access to gain and zero-scale cali-
bration registers allows system-level offset and gain cal-
ibration. The zero-scale adjustment register allows
intentional positive offset skewing to preserve unipolar-
mode resolution for signals that have a slight negative
