Term Description
SNR The ratio of the output signal voltage level to the output noise level.
THD The ratio of the sum of powers of the harmonic frequency components to the power of the fundamental/original frequency component.
SFDR Characterizes the ratio between the fundamental signal and the highest spurious in the spectrum.
SINAD The ratio of the RMS value of the signal amplitude to the RMS value of all other spectral components, including harmonics, but excluding DC.
ENOB The number of bits with which the ADC behaves.
DNL The maximum and minimum difference in the step width between actual transfer function and the perfect transfer function
INL The maximum vertical difference between the actual and the ideal curve. It indicates the amount of deviation of the actual curve from the ideal transfer curve.
