NOTES: (1) In order to achieve the converter’s full-scale range, the input must be fully differential. If the input is single-ended (+V
or –V
is fixed), then the
full-scale range is one-half that of the differential range. (2) Applies to full-differential signals. (3) The common-mode rejection test is performed with a 100mV
differential input.
