ADS1115 with ntc thermistor

Martin-X:
That is correct, you will need to know the supply voltage to calculate the resistance. However, the voltage read by the ADC is not supply dependant.

Should be replaced with

Thank you very much! so once i've calculated Vout

Vout = ADC_Value  * 0.0001875;

i can use it in the formula

Rth + 10k = VCC * 10k / Vout

to calculate resistence and then use this

Temperature(in kelvin) = 1 / (A + B[ln(Rth)] + C[ln(Rth)]^3)

to get temperature?
