1 LSB = 4.88 mV for 0 V to +1.25 V output range, 9.76 mV for 0 V to +2.5 V and
±
1.25 V ranges and 19.5 mV for
±
2.5 V range.

Includes internal voltage reference error and is calculated after offset error has been adjusted out. Ideal unipolar full-scale voltage is (FS – 1 LSB); ideal bipolar positive full-scale voltage is (FS/2 – 1 LSB)
and ideal bipolar negative full-scale voltage is –FS/2.
