Note:

INL and DNL are referenced to a LSB of the Equivalent ADC Bits shown in the last row of

Table 38. 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 39 lists other specifications for the ADC not covered in Table 37 and Table 38.
