Typical Performance
Note: The graphs and tables provided following this note are statistical summary based on limited number of
samples and are provided for informational purposes only. The performance characteristics listed herein are not
tested or guaranteed. In some graphs or tables, the data presented may be outside the specified operating
range and therefore outside the warranted range.
Linearity
Integral Non-Linearity
The different PGA stages have been designed to find the best compromise between the noise performance, the
integral non-linearity and the power consumption. To obtain this, the first stage has the best noise performance
and the third stage the best linearity performance. For large input signals (small PGA gains, i.e. up to about 50),
the noise added by the PGA is very small with respect to the input signal and the second and third stage of the
PGA should be used to get the best linearity. For small input signals (large gains, i.e. above 50), the noise level
in the PGA is important and the first stage of the PGA should be used.
The following figures show the Integral non linearity for different gain settings over the chip temperature range.
