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.
