This error may be reduced by repeatedly sampling the input and averaging the result.
Additionally, the techniques discussed in Noise-induced errors reduces this error.
• Non-monotonicity: Non-monotonicity is defined as when, except for code jitter, the
converter converts to a lower code for a higher input voltage.
• Missing codes: Missing codes are those values never converted for any input value.
In 8-bit or 10-bit mode, the ADC is guaranteed to be monotonic and have no missing
codes.
