Normal Case 2: VSENSE ≥ 20 mV, VCM < VS

This region of operation has slightly less accuracy than Normal Case 1 as a result of the common-mode operating area in which the device functions, as illustrated in the Output Error vs Common-Mode Voltage curve (Figure 6). As noted, for this graph VS = 12 V; for VCM < 12 V, the output error increases when VCM becomes less than 12 V, with a typical maximum error of 0.005% at the most negative VCM = –16 V.
