a. The conversion rate = Sample rate * 512.
b. The total frequency response is the combined frequency response of the ADC Sigma Delta filter and the analog filter.
c. Channel 0 is the reference channel with a 20 V PP signal and a maximum sample rate of 52.734 kSamples/s.
d. Cable capacitance of typically 30 pF per foot must be added.
e. Offset errors are referred to the input.
f. ENOB, SINAD, SNR, THD, and SFDR measurements were made with a 16384 point FFT with a minimum 4-term Blackman Harris window.
