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.

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 output of U2, and the output is shown in green in the graph sorry for the poor quality.

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.

If you have a simulator handy it’s easy to simulate. And as a result this internal output impedance would behave like the ”series” resistor or that’s incorrect?

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

There is a DC limit usually of datasneet to k. Sign up or log in Sign up using Google.

The absolute continuous ratings for the TL state that the output short-circuit duration is ‘continuous’. Even feedback resistors can be regarded as a load – anything that takes current from the output pin.

In my understanding the zener should face the whole sinusoidal wave since there’s no resistor in series to share the remaining voltage with. The output impedance assessment in your question I think is based on this: Email Required, but never shown. The low output impedance you quoted is conditional on the output stage not being overloaded.

I guess I’ve datasbeet the vatasheet. Sign up using Email and Password. I tried that on real circuits with TL OpAmp and the same happened. 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. Home Questions Tags Users Unanswered. Looking at Figure 7 the positive current limit applicable to your design is 20 mA 1b4728 temperature dependent.

Andy aka k 10 This means that there is current limiting built in.

Thank you for any help. I’ve also checked the TL output resistance and it’s about 0. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Tony EE rocketscientist 62k 2 21 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.
