Multiplexed ADCs connect many analog input channels to a single ADC. The ADC can then scan through the multiple input channels either continuously or in bursts based on an external trigger (many times an ePWM trigger in C2000 applications).
For the sake of charge-sharing, the sample rate on a given channel is important, not the full sample rate of the ADC. This is because charge-sharing equalization will only occur when the particular multiplexed channel is sampled and the source capacitance will have the entire time between sampling to recharge, even if other channels are sampled in the meantime. In applications where the ePWM is triggering the ADC periodically, the sample rate on a given multiplexed channel will match the ePWM triggering frequency.
