NOTES:
1. Ideal input span; does not include gain or offset error.
2. LSB means least significant bit.
3. Measured relative to an ideal full-scale input.
4. Calculated on the first nine harmonics of the input frequency.
5. Device is designed to operate over V
due to SNR degradation resulting from lowered signal range.
