Settings to be given to make a single channel SAR ADC operate at 1Msps
I am not sure if all of you are aware of this. You need to configure Vref to "Internal 1.024 V bypassed" from the drop-down list in SAR ADC to obtain 1Msps of conversion rate. Also averaging option has to be disabled.
One important point to be noted is that to obtain exact 1Msps sampling rate, the IMO should be configured to be 36 MHz.
