INL and DNL are referenced to a LSB of the Equivalent ADC Bits shown in the last row of Table 10-6. ENOB
(effective number of bits) can be calculated from either SNR (signal to non-harmonic noise ratio) or SINAD
(signal-to-noise and distortion ratio).
Table 10-9 lists other specifications for the ADC not covered in Table 10-6 and Table 10-7.
