NOTES: (1) Typically the tolerance of RG will be the major source of gain error. (2) Nonlinearity is the maximum peak deviation from the best straight-line as a percentage of peak-to-peak full scale output. (3) Not including the TCR of RG. (4) Adjustable
to zero at any one gain. (5) θJC output stage = 113°C/W, θJC quiescent circuitry = 19°C/W, θCA = 83°C/W.
