Tony EE rocketscientist 62k 2 21 It made my thoughts clearer now. The low output impedance you quoted is conditional on the output stage not being overloaded.

The small signal output impedance is due to the op-amp open-loop gain not being infinite. I tried that on real circuits with TL OpAmp and the same happened.

Sign up using Facebook. I guess I’ve gotten the idea. It has been clearer since the first comment up to now. I would design for 10 mA maximum. 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. I know it’s not clearly stated that it is for small signals but it’s something that you get used to seeing and understanding.

There is a DC limit usually of k to k. Could I think of the situation as a dynamic output impedance being changed when the current begins to be limited by the opamp?

Even feedback resistors can be regarded as a load – anything that takes current from the output pin. Yet, the real question is I don’t get the fact the zener is being able to clamp the output voltage without a resistor in series with it.

And as a result this internal output impedance would behave like the ”series” resistor or that’s incorrect?

dataaheet The absolute continuous ratings for the TL state that the output short-circuit duration is ‘continuous’. I’ve also checked the TL output resistance and it’s about 0. Home Questions Tags Users Unanswered. So, what exactly is going on in this circuit? Looking at Figure 7 the positive current limit applicable to your design is 20 mA but temperature dependent.

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: 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.

The output impedance assessment in your question I think is based on this: What exactly would be the loading in this case? Now I have the same circuit but with that 1N zener connected across and the output signal behaves like below:
