A charge-redistribution successive-approximation analog-to-digital converter includes means for scaling an unknown analog input voltage (V.sub.IN) whose maximum rated value is greater than the precision reference voltage (V.sub.REF) of the converter. The unknown input voltage is applied to selected charge storing means, forming the charge-redistribution network, during a sampling interval. Subsequently, the charge on the selected charge storing means is distributed to additional charge storing means to produce the desired degree of scaling. The scaling factor is proportional to the ratio of V.sub.REF to the maximum rated value of V.sub.IN.
