Once enabled the SDADC keeps running. There is no “Single conversion mode”. This requires converted data to be continually drained by DMA or ISR. The digital nature of the SDADC means that there is a propagation delay as the data is clocked through the internal digital filters. This has to be taken into account at startup or at any channel mux change. This latency means that the SDADC is not well suited to some applications including motor control. When used in an AC sampling application it is likely that each SDADC will have to be dedicated to a particular input rather than switching the input channel.
SDADC offers higher conversion accuracy (16-bit result).
You have 4 SDADC modules available, ideal condition is every SDADC to be assigned to one channel. Or use eQADC module as this is ideal for switching channels.
