In the factory, the CS5101A and CS5102A are
tested using Fast Fourier Transform (FFT) tech-
niques to analyze the converters' dynamic perfor-
mance. A pure sine wave is applied to the device,
and a “time record” of 1024 samples is captured
and processed. The FFT algorithm analyzes the

spectral content of the digital waveform and distrib-
utes its energy among 512 “frequency bins.” As-
suming an ideal sine wave, distribution of energy in
bins outside of the fundamental and DC can only
be due to quantization effects and errors in the
CS5101A and CS5102A.
