Notes:
1.
Full-scale input voltage denotes the differential input signal amplitude (V_IN-VRLC in non-CDS mode, V_IN-RESET
level in CDS mode) that can be gained to match the ADC full-scale input range.
2.
Input signal limits are the limits within which each input voltage and VRLC reference must lie.
