MAX194
14-Bit, 85ksps ADC with 10A Shutdown
Spurious-Free Dynamic Range
Spurious-free dynamic range is the ratio of the funda-
mental RMS amplitude to the amplitude of the next
largest spectral component (in the frequency band
above DC and below one-half the sample rate). Usually,
this peak occurs at some harmonic of the input frequen-
cy. However, if the ADC is exceptionally linear, it may
occur only at a random peak in the ADC’s noise floor.
Transfer Function
Figures 28 and 29 show the MAX194’s transfer func-
tions. In unipolar mode, the output data is in binary for-
mat and in bipolar mode it is offset binary.
