    is the psoc 4m only a 11 bit a/d resolution in single channel

    glenn-edgar_1523231

      In single channel mode for the SAR_ADC, ( psoc 4m ), the max value appears to be 2047.  This is a 11 bit value.  It looks like the a/d is still acting like the a/d is running in differential mode, ie -2047 to 2047.  Sometime the ground measurement returns -1, which seems to indicate that a differential mode measurement is returned.

         

       

         

      Is there a way to have the A/D return 0 to 4095, which is a 12 bit a/d range.
