Post as a guest Name. You beat out Null by 1 minute. Maybe some of the parameters in the datasheet can point out why this is happening. Sign up or log in Sign up using Google.

I cannot figure out why the outputs for the amplifiers are different. 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 datasneet. Sign up using Facebook.
The minimum supply voltage for an LM is 10 volts – you have it powered at 5 volts. You’ve only provided 5V. 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.

Email Required, but never shown. 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. Home Questions Tags Users Unanswered. Null 4, 10 22 Zero on non-inverting input for non-inverting amplifier gives output different than zero Ask Question.
Can somebody please explain me the difference between outputs on both amplifiers. Schematic and DC operating point is showed in the image.
I know that there should be some input offset voltage that is amplified, but the interesting part datashet that the output voltage does not depend on the closed loop gain formed by R3 and R4 and R5 and R6 for the other amplifier. The LM will work quite happily down datasheft 3 volts but you have other errors It is probably written somewhere in the datasheet, but I do not know where. Do things like this get better at lower supply voltage?
