PRODUCTION DATA
Channel 3 of the CCS is used to measure the die temperature of the device. The ADC measures an internal temperature sensor that measures a voltage complementary to the absolute temperature (CTAT). This CTAT voltage has a negative temperature coefficient. The ADC converts this voltage at a data rate of 2560 Hz. When the ADC conversion is completed, the data are found in the ADC_TEMP.DATA bits (address 26h).
The relationship between the ambient temperature and the ADC code is shown in Equation 8:
