ENOB indicates the global accuracy of an ADC at a
specific input frequency and sampling rate. With an
input range equal to the ADC’s full-scale range, calcu-
late the ENOB as follows:
For the MAX1032/MAX1033, THD is the ratio of the
RMS sum of the input signal’s first four harmonic com-
ponents to the fundamental itself. This is expressed as:

SFDR is the ratio of RMS amplitude of the fundamental
(maximum signal component) to the RMS value of the
next-largest spectral component.
