NOTES: (1) All typical values are at TA = +25°C. (2) Ensured by design. (3) Integral nonlinearity is defined as one-half the peak-to-peak deviation of the best fit
line through the transfer curve for VIN+ = –250mV to +250mV, expressed either as the number of LSBs or as a percent of measured input range (500mV). (4) Only
typical information parameter not tested.
