Forum Post: RE: ADS1219: External Reference Voltage Selection
Hi Koji, VREF can con go all the way up to your Analog supply AVDD: You can simply make REFP = AVDD and REFN = GND. This would make your VREF 5V since AVDD = 5V. This should cover your analog input...

Hi Karthik, The external anti-aliasing filter is designed to attenuate aliasing from the modulator frequency, not the sampling frequency, since the signal noise at the sampling frequency is already...
