For unipolar mode (AVDD=5V, AVSS=0V, VREFP=5V, VREFN=0V), ADS1282 full-scale input voltage is from 0V to 2.5V. Am i right?
Also data code is range from 00000000h to 7FFFFFFFh for FIR filter. Am i right?
Most of data in the datasheet is according to unipolar mode. Thus, i'm not sure about this subject.
