I wouldn’t see it so easily like you did in the datasheet, thank you very much. The small signal output impedance is due to the op-amp open-loop gain not being infinite. I’ve also checked the TL output resistance and it’s about 0.

1N Datasheet PDF –

I tried that on real circuits with TL OpAmp and the same happened. It made my thoughts clearer now.

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 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.

However, this is a “small signal” graph. It’s a calculated graph based on the open-loop gain graph and the amount of gain datahseet particular op-amp may be configured for. Post as a guest Name.


Could I think of the situation as a dynamic output impedance being changed when the current begins to be limited by the opamp?

Tony EE rocketscientist 62k 2 21 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: 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.

If you have a simulator handy it’s easy to simulate.

I would design for 10 mA maximum. Even feedback resistors can be regarded as a load – anything that takes current from the output pin. And as a result this internal output impedance would behave like the ”series” resistor or that’s incorrect? Now I have the same circuit but with that 1N zener connected across and the output signal behaves like below: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Thank you for any help. There is a DC limit usually of k to k.

This means that there is current limiting built in. The output impedance assessment in your question I think is based on this: What exactly would be the loading in this case?


Shouldn’t a zener have a series resistor in order to clamp correctly? Sign up using Facebook. Not sure if this answers your comment?

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.

Home Questions Tags Users Unanswered. Iron Maiden 7. 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. Looking at Figure 7 the positive current limit applicable to your design is 20 mA but temperature dependent.

The absolute continuous ratings for the TL state that the output short-circuit duration is ‘continuous’. The low output impedance you quoted is conditional on the output stage not being overloaded. So, what exactly is going on in this circuit? I guess I’ve gotten the idea. Sign up using Email and Password.
