Analog-to-Digital Converter (S08ADC10V1)
converter yields the lower code (and vice-versa). However, even very small amounts of system noise can
cause the converter to be indeterminate (between two codes) for a range of input voltages around the
transition voltage. This range is normally around ±1/2
and will increase with noise. This error may be
LSB
reduced by repeatedly sampling the input and averaging the result. Additionally the techniques discussed
in
Section 8.6.2.3, “Noise-Induced
Errors,” will reduce this error.
Non-monotonicity is defined as when, except for code jitter, the converter converts to a lower code for a
higher input voltage. Missing codes are those values which are never converted for any input value.
In 8-bit or 10-bit mode, the ADC is guaranteed to be monotonic and to have no missing codes.
