The TMP36 datasheet refers to an offset voltage of 0.5V but it's not obvious what this refers to, please explain?
For TMP36 it just means that in order to convert voltage into temperature, simply use the basic formula:
Temp in °C = [(Vout in mV) - 500] / 10
So for example, if Vout is 1V that means that the temperature is ((1000 mV - 500) / 10) = 50 °C
Compared to TMP35 and TMP37, this offset had to be used to get the TMP36 to work at negative temps.
