for a sampling clock of 1 MHz. ADC_HVSELP and ADC_HVSELN are programmed to 0 to
disable the input buffer. The single-ended measurements were done at f
0 dBFS level (where full-scale is a 1.2 V p-p swing). The differential measurements were
done at f

Equivalent ADC Bits
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).
