The LM datasheet says it can be powered by a minimum of a 3V single supply, so it works. You beat out Null by 1 minute. Sign up using Facebook.

You’re also violating the common mode input voltage range for the LM by grounding the non-inverting input and using ground as lj318 VSS rail. Stjepan Gornik 3 3. Do things like this get better at lower supply voltage? Schematic and DC operating point is showed in the image.

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. Also, the output can only swing to within 3V of the rails. Zero on non-inverting input for non-inverting amplifier gives output different than zero Ask Question.

Maybe some of the parameters in the datasheet can point out why this is happening.

You’ve only provided 5V. It is probably written somewhere in the datasheet, but I do not know where. Post as a guest Name. Email Required, but never shown.

Can somebody please explain me the difference between outputs on both amplifiers. I cannot figure out why the outputs for the amplifiers are different.

dagasheet Null 4, 10 22 The minimum supply voltage for an LM is 10 volts – you have it powered at 5 volts. Andy aka k 10
