The absolute continuous ratings for the TL state that the output short-circuit duration is ‘continuous’. However, this is a “small signal” graph. Thank you for any help.

I’ve also checked the TL output resistance and it’s about 0. If you have a simulator handy it’s easy to simulate.

Looking at Figure 7 the positive current limit applicable to your design is 20 mA but temperature dependent. I wouldn’t see it so easily like you did in the datasheet, thank you very much. It has been clearer since the first comment up to now. 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.

Could I think of the situation as a dynamic output impedance being changed when the current begins to be limited by the opamp? The output impedance assessment in your question I think is based on this: The low output impedance you datasheett is conditional on the output stage not being overloaded. 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.

Fatasheet 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. Home Questions Tags Users Unanswered.

There is a DC limit usually of k to k. Iron Maiden 7.

Sign up using Facebook. In my understanding the zener should face the whole sinusoidal wave since there’s no resistor in series to share the remaining voltage with. Sign up or log in Sign up using Google.

This means that there is current limiting built in. 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. 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 datzsheet to become clamped at around the zener point.

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 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 datashewt a given load resistance:
