I've connected an op-amp (TL071) as buffer, with Vcc+ = 5V and Vcc- = 0V (ground).
When the input voltage (v+) is greater than 1.44V I get the expected result (the output is the same as the input).
However, if the input is below 1.44V, the output saturates.
Anyone knows why this might be and how can I get around it? My goal was to amplify the signal of a LM35 (a temperature measurement).
