for a sampling rate of 6 MHz. ADC_HVSELP and ADC_HVSELN are programmed to 1 to
enable the input buffer. The single-ended measurements were done at f
level = 1.2 V p-p swing centered on 1.5 V. The differential measurements were done at

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).
