I have a LM335 that I would use with an ATmega168 to measure an indoor temperature, in the range 250K..313K (-23°C...+40°C) so the voltage swing is 0.25V..0.313V.
Was wondering if I can attach directly the sensor to ADC input of ATmega168 or I have to use a conditioning stage (to bring the voltage swing to 0..5V)
The resolution needed is 1°C
Thansk in advance
