NOTES: (1) Ideal input span, does not include gain or offset error. (2) LSB means Least Significant Bit, with VREF equal to +2.5V, one LSB is 1.22mV. (3) Measured
relative to an ideal, full-scale input (+In – (–In)) of 4.999V. Thus, gain error includes the error of the internal voltage reference. (4) Calculated on the first nine
harmonics of the input frequency. (5) If the internal reference is required to source current to an external load, the reference voltage will change due to the internal
10k
resistor. (6) Can vary ±30%.
