There are several things dahasheet 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 output impedance assessment in your question I think is based on this: Thank you for any help.

I tried that on real circuits with TL OpAmp and the same happened.

Email Required, but never shown. However, this is a “small signal” graph. It made my thoughts clearer now. The low output impedance you quoted is daatsheet on the output stage not being overloaded. Sign up using Email and Password. Iron Maiden 7. Even feedback resistors can be regarded as a load – anything that takes current from the output pin.

There is a DC limit usually of k to k. Shouldn’t a zener have a series resistor in order to clamp correctly? 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.


Post as a guest Name. Home Questions Tags Users Unanswered. I guess I’ve gotten the idea. Not sure if this answers your comment? I wouldn’t see it so easily like you did in the datasheet, thank you very much.

Here I have the image of a signal in the datzsheet of U2, and the output is shown in green in the graph sorry for the poor quality. Sign up or log in Sign up using Google.

It has been clearer since the first comment up to now.

I would design for 10 mA maximum. 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. This means that there is current limiting built 14728.

Tony EE rocketscientist 62k 2 21 Sign up using Datasehet. 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’.

Could I think of the situation as a dynamic output impedance being changed when the current begins to be limited by the opamp? 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. What exactly would be the loading in this case? And as a result this internal output impedance would behave like the ”series” resistor or that’s incorrect? In datasueet understanding the zener should face the whole sinusoidal wave since there’s no resistor in series to share the remaining voltage with. It’s 1n44728 calculated graph based on the open-loop gain graph and the amount of gain a particular op-amp may be configured for.

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.

Now I have the same circuit but with that 1N zener connected across and the output signal behaves like below: So, what exactly is going on in this circuit?

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