I will be using the PGA309 with a thermistor for temperature sensing. I plan to use the on board 7 uA current source which gives a voltage at the thermistor of about 0.003 volts to 2.363 volts for a 165 degC swing in temperature. I am setting the temp ADC reference to the 4.096 volt option and the ADC gain to 1.
I would like to have an idea how close the accurate the temperature will be. How many bits is the temp ADC?
