Hi all, I'm trying to read a thermistor using an external ADC with 16 bit precision, the ADS1115. Accuracy is important to me so I've also employed an LM4040 to provide a very steady voltage, specifically I used the model that is supposed to take a 3v3 input and give a 2v048 output.
My main issue here is that every document I've ready discussing how to convert the mV analog reading into a Resistance value assumes that the entire circuit is 5V so it cancels out two voltage readings at some point leaving the equation
R = SeriesResistor / ((2^BitOfPrecision - 1) / ADC_Reading - 1)
R = 10K / (1023 / (ADC_Reading - 1))
How can I correctly modify this formula to reflect the fact that my Vcc (3v3) is different than my actual analog input (1v526)
