Ideal input span, does not include gain or offset error.
LSB means least significant bit
This is endpoint INL, not best fit
Measured relative to an ideal full-scale input [+IN – (–IN)] of 8.192 V
This specification does not include the internal reference voltage error and drift.
Calculated on the first nine harmonics of the input frequency
