I cannot figure out why the outputs for the amplifiers are different. It is probably written somewhere in the datasheet, but I do not know where. Maybe some of the parameters in datsaheet datasheet can point out why this is happening. Schematic and DC operating point is showed in the image.
The minimum supply voltage for an LM is 10 volts – you have it powered at 5 volts. The LM will work quite happily down to 3 volts but you have other errors You are expecting the LM to operate with its inputs at the most negative rail i. Notice also the output voltage spec – it tells you that the output isn’t guaranteed to get to within 3 volts of either power rail.
You’re also violating the common mode input voltage range for the LM by grounding the non-inverting input and using ground as the VSS rail.

Do things like this get better at lower supply voltage? Andy aka k 10 You beat out Null by 1 minute. You’ve only provided 5V. Also, the output can only swing to within 3V of the rails.
