Part Number: ADS131E08 hi, I am using ADS131E08 for voltage measurement in my project.I will be sampling at 8 kHz. The low pass anti aliasing filter cut off frequency should be less than 4 kHz, according to NYQUIST criteria. I have query regarding the ADC. The ADC is sigma delta ADC. Does it follow nyquist criteria.? Whether the sampling frequency can be lower than the low pass filter cut off frequency?. Kindly inform about the cut off frequency requirements for the low pass filter at 8kHz.
