There are several things to consider as Transistor points out and another consideration is this graph – how much output voltage swing you can get for a given load resistance: The dataaheet output impedance you quoted is conditional on the output stage not being overloaded. And as a result this internal output impedance would behave like the ”series” resistor or that’s incorrect? Thank you for any help.

Email Required, but never shown. Iron Maiden 7. I know it’s not clearly stated that it dataxheet for small signals but it’s something that you get used to seeing and understanding. I’ve also checked dataseet TL output resistance and it’s about 0. So, what exactly is going on in this circuit? Now I have the same circuit but with that 1N zener connected across and the output signal behaves like below: It’s a calculated graph based on the open-loop gain graph and the amount of gain a particular op-amp may be configured for.

I wouldn’t see it so easily like you did in the datasheet, thank you very much. Sign up using Facebook. Looking at 1h4728 7 the positive current limit applicable to your design is 20 mA but temperature dependent.

Yet, the real question is I don’t get the fact the datazheet is being able to clamp the output voltage without a resistor in series with it.

Not sure if this answers your dahasheet I tried that on real circuits with TL OpAmp and the same happened.

Here I have the image of a signal in the output of U2, and the output is shown in green in the graph sorry for the poor quality.

However, this is a “small signal” graph.

If you have a simulator handy it’s easy to simulate. The small signal output impedance is due to the op-amp open-loop gain not being infinite.

Tony EE rocketscientist 62k 2 21 Could I think of the situation as a dynamic output impedance being changed when the current begins to be limited by the opamp? I guess I’ve gotten the idea. Even feedback resistors can be regarded as a load – anything that takes datasheett from the output pin. The output impedance assessment in your question I think is based on this: Home Questions Tags Users Unanswered.

What exactly would be the loading in this case? It has been clearer since the first comment up to now.

In my understanding the zener should face the whole sinusoidal wave since there’s no resistor in series to share the remaining voltage with.

There is a DC limit usually of k to k. I would design for 10 mA maximum. As the zener voltage starts to be exceeded, the load resistance that it produces drops rapidly down to a few tens of ohms so, as per the graph above you would expect the voltage to become clamped at around the zener point.
