    PSOC 4 Die Temperature Measurement


      I am not getting good die temperature measurements.


      I have the voltage reference set to vda/2 and as a negative reference.  This gives me a 12 bit voltage range from vda of ground.  The values being 2048 to -2048. 


      Can the die temperature measurement be used in such a configuration?


      If so, then is the following equation to correct for voltage references that are not 1024 is to multiply the a/d counts by vref/1.024v?


      Also what is vref.  Is it vda or vda/2.
