SFDR, SINAD, and ENOB) of the ADS1278 ADC through single-tone sinusoidal signal FFT analysis using
the 7-term Blackman-Harris window setting. The FFT tool includes windowing options that are required to
mitigate the effects of non-coherent sampling (this discussion is beyond the scope of this document). The
7-Term Blackman-Harris window is the default option and has sufficient dynamic range to resolve the frequency
components of up to a 24-bit ADC. The None option corresponds to not using a window (or a rectangular
window) and is not recommended.
