Zero on non-inverting input for non-inverting amplifier gives output different than zero Ask Question. 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.
Can somebody please explain me the difference between outputs on both amplifiers. 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. Null 4, 10 22 Sign up or log in Sign up using Google.
Do things like this get better at lower supply voltage? It is probably written somewhere in the datasheet, but I do not know where.
You beat out Null by 1 minute. Sign up using Email and Password. The LM datasheet says it can be powered by a minimum of a 3V single supply, so it works.

Maybe some of the parameters in the datasheet can point out why this is happening. Schematic and DC operating point is showed in the image. Also, the output can only swing to within 3V of the rails. You are expecting the LM to operate with its datasjeet at the most negative rail i.
I cannot figure out why the outputs for the amplifiers are different.
The LM will work quite happily down to 3 volts but you have other errors Email Required, but never shown. The minimum supply voltage for an LM is 10 volts – you have it powered at 5 volts. Stjepan Gornik 3 3. Post as a guest Name. Sign up using Facebook.
