Supply Voltage Sensor
The supply voltage sensor transfer function is:
To calculate the AVDD supply voltage from the ADC result value:
where R is the ADC conversion result, V
supply voltage sensor division factor, nominally 13/8 = 1.625.
Temperature Sensor
This table lists the performance characteristics of the on-chip temperature sensor over the full range of
process variation, operating temperature and supply voltage.
