Hi,
I am working on a temperature controller based on LM35 (Temperature sensor) and interfaced to PIC microcontroller ADC, with 5V as reference for ADC.
To increase the resolution of my signal from LM35, I have added an amplifier -- LM358, with a gain of 11 and supply of +5V and 0V.
My problem is that the output of LM358 (op-amp) saturates at 3.707V. I know that LM358 is not a rail-to-rail Op-amp, but I never expected the output to saturate at 3.707V (when supply is +5V and 0V). I decided to reduce the gain of amplifier so that the output never reaches 3.707V for my application need.
My query --
Where do I get this figure 0f 3.707V output saturation in the data sheet of LM358 (that will help me to figure out such error during design of any other project)?
