1 LSB = 4.88 mV for 0 V to +1.25 V 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.
4
See Terminology.
5
Includes internal voltage reference error and is calculated after offset error has been adjusted out. Ideal unipolar last code transition occurs at (FS – 3/2 LSB). Ideal bipolar last code transition occurs at
(FS/2 – 3/2 LSB).
6
Exact frequencies are 101 kHz and 384 kHz to avoid harmonics coinciding with sampling frequency.
