11.3.2 Differential Non-Linearity
The differential non-linearity is generated by the ADC. The PGA does not add differential non-linearity.
the differential non-linearity.
11.4 Noise
Ideally, a constant input voltage V
output code may vary for a fixed input voltage. Thus, a statistical analysis on the output code of 1200 conversions for a
constant input voltage was performed to derive the equivalent noise levels of PGA1, PGA2, and PGA3.
The extracted RMS output noise of PGA1, 2, and 3 are given in
output rms noise voltage.
