National Semiconductor – datasheet pdf

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. Also, the output can only swing to within 3V of the rails.

The LM will work quite happily down to 3 volts but you have other errors Andy aka k 10 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.

Schematic and DC operating point is showed in the image. Home Questions Tags Users Unanswered.

Stjepan Gornik 3 3. 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. Email Required, but never shown. You beat out Null by 1 minute.

Do things like this get better at lower supply lj318 I know that there should be some input offset voltage that is amplified, but the interesting part is that the ln318 voltage does not depend on the closed loop gain formed by R3 and R4 and R5 and R6 for the other amplifier.

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. Sign up using Email and Password.

The minimum supply voltage for an LM is 10 volts – you have it powered at 5 volts. You are expecting the LM to operate with its inputs at the most negative rail i. lm18

Null 4, 10 22 The LM datasheet says it can be powered by a minimum of a 3V single supply, so it works. You’ve only provided 5V. Can somebody please explain me the difference between outputs on both amplifiers. Sign up using Facebook.
