I would like to connect a temperature sensor to the ADC (TOUT) pin. What's the max voltage ADC can read? Is it 1V? If yes, does applying a 2V voltage to the ADC damages the ESP8285? Between 0ºC and 80ºC the voltage will go from 1V to almost 0V, but below 0ºC the voltage will go up to 1.5V or 2V. This kind of voltage on ADC pin could damage the ESP8285 chip? We don't need to measure below 0ºC so it it's safe we don't mind reading always the max value (1024) from the ADC.
Looking forward to hearing from you soon,
No huge addition to system cost either!
