For high voltage applications, multi-channel successive approximation register (SAR) analog-to-digital converters (ADCs) are often plagued with numerous problems that are generally associated with parasitics (which are present in high voltage components). Here, a different architecture is provided where the sampling capacitors are separated from conversion capacitors so as to have low voltage components in the conversion path. Additionally, to improve the acquisition time and reduced total harmonic distortion (THD) multiple channels can use the same sampling capacitors.
