NOTES: (1) For further information, refer to typical performance curves on common-mode input range. (2) Operation beyond (V+) – 1.8V (max) results in reduced common-mode
rejection. See discussion and Figure 6 in the text of this data sheet. (3) Does not include error and TCR of additional optional gain-setting resistor in series with R
G
, if used.
