SPC58xx SAR ADC
■The aim of this document is to clarify the usage and features of the SAR ADC found inside the chips in the SPC58 family, and help the user to design the external components to achieve the desired level of precision of the sampled signals.
■In particular, it is important to reject as much noise as possible from the reference voltage, as its variations will directly affect the accuracy of the conversion.
■The accuracy of the conversion is usually measured in LSBs, which is the highest order bit that is different from the actual value.For example, if the “real” value were 10010100 but an error caused it to be measured as 10010000, we would have an error of 3 LSBs, since the error involves the third least significant bit.
