Stjepan Gornik 3 3. Email Required, but never shown. The minimum supply voltage for an LM is 10 volts – you have it powered at 5 volts.

Maybe some of the parameters in the datasheet can point out why this is happening. You’ve only provided 5V.
I know that there should be some input offset voltage that is amplified, but the interesting part is 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.
It is probably written somewhere in the datasheet, but I do not know where.
Zero on non-inverting input for non-inverting amplifier gives output different than zero Ask Question. Sign up using Facebook.
The LM daatasheet work quite happily down to 3 volts but you have other errors Sign up using Email and Password. You are expecting the LM to operate with its inputs at the most negative rail i. You beat out Null by 1 minute. Andy aka k 10 The LM datasheet says it can be powered by a minimum of a 3V single supply, so it works.

I cannot figure out why the outputs for the amplifiers are different. Sign up or log in Sign up using Google.

Also, the output can only swing to within 3V of the rails. Schematic and DC operating point is showed in the image.
