Ok, that is very good!
dc42:
The nominal voltage across the LM335 is 10mv per degree Kelivin, as specified in the datasheet.
This is similar to the formula for LM35 where 10mV correspond 1°C temperature change.
But why does this one need a 2K resistor while LM35 doesn't need one. Does that mean that LM335 is only the thermistor?
Why does this one have 3 pins (it is also called LM335 ) ?
