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. Now I have the same circuit but with that 1N zener connected across and the output signal behaves like below: Yet, the real question is I don’t get 1h4728 fact the zener is being able to clamp the datasheeet voltage without a resistor in series with it. In my understanding the zener should face the whole sinusoidal wave since there’s no resistor in series to share the remaining voltage with.

I tried that on real circuits with TL OpAmp and the same happened. I’ve also checked the TL output resistance and it’s about 0. Datasheer, what exactly is going on in this circuit?

Shouldn’t a zener have a series resistor in order to clamp correctly? The absolute continuous ratings for the TL state that the output short-circuit duration is ‘continuous’.

This means that there is current limiting built in. The low output impedance you quoted is conditional on the output stage not being overloaded. Looking at Figure 7 the positive current limit applicable to your design is 20 mA but temperature dependent.

I would design for 10 mA maximum. 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 datashheet 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 1m4728 impedance assessment in your datashedt I think is based on 1m4728 However, this is a “small signal” graph. 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. 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.

Iron Maiden 7. It made my thoughts clearer now. I wouldn’t see it so easily like you did in the datasheet, thank you very much. Andy aka k 10 Could I think of the situation as a dynamic output impedance being changed when the current begins to be limited by the opamp? And as a result this internal output impedance would behave like the ”series” resistor or that’s incorrect?

The small signal output impedance is due to the op-amp open-loop gain not being infinite. There is a DC limit usually of k to k. Not sure if this answers your comment? What exactly would be the loading in this case?

Even feedback resistors can be regarded as a load – anything that takes current from the output pin. If you have a simulator handy it’s easy to simulate. I guess I’ve 1n428 the idea.
