Hi Wagner,

I'll have to admit ignorance as to how linear NTCs are. What I was saying
is that it seems to me that it is totally unnecessary to introduce
additional non-linearity by using it in a voltage divider configuration.
One could simply use it with a transimpedance amp. Then, any nonlinearity
that you have comes only from the NTC itself, not from the voltage divider
equation.
