11.3.2 Differential Non-Linearity
The differential non-linearity is generated by the ADC. The PGA does not add differential non-linearity. Figure 45 shows
the differential non-linearity.
11.4 Noise
Ideally, a constant input voltage VIN should result in a constant output code. However, because of circuit noise, the
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 Table 39, page 56: standard output deviation and
output rms noise voltage.
