This is the Absolute Value of Input Offset Change vs. Temperature. b. Gain is defined as the slope of the best-fit line of differential output voltage (VOUT+ – VOUT–) vs. differential input voltage (VIN+ – VIN–) over the specified input range. c. This is the Absolute Value of Gain Change vs. Temperature. d. Nonlinearity is defined as half of the peak-to-peak output deviation from the best-fit gain line, expressed as a percentage of the full-scale differential output voltage. e. NL100 is the nonlinearity specified over an input voltage range of ±100 mV. f. The input supply current decreases as the differential input voltage (VIN+ – VIN–) decreases.
