Thank you for any help. Sign up using Facebook.

Iron Maiden 7. Looking at Figure 7 the positive current limit applicable to your design is 20 mA but temperature dependent. There is a DC limit usually of k to k. Shouldn’t a zener have a series resistor in order to clamp correctly?

This means that there is current limiting built in. I would design 1h4728 10 mA maximum. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

The small signal output impedance is due to the op-amp open-loop gain not being infinite. 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. Vatasheet output impedance assessment in your question I think is based on this: So, what exactly is going on in this circuit?

Now I have the same circuit but with that 1N zener connected across and the output signal behaves like below: Post as a guest Name. Even feedback datasheeh can be regarded as a load – anything that takes current from the output pin.

Could I think of the situation as a dynamic 1m4728 impedance being changed when the current begins to be limited by the opamp? The absolute continuous ratings for the TL state that the output short-circuit darasheet is ‘continuous’.

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: By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies. Yet, the real question dahasheet I don’t get the datashedt the zener is being able to clamp the output voltage without a resistor in series with it.

If you have a simulator handy it’s easy to simulate. 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. Andy aka k 10 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.

What exactly would be the loading in this case? Sign up or log in Sign up using Google.

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 know it’s not clearly stated that it is for small datasneet but it’s something that you get used to seeing and understanding.

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. I guess I’ve gotten the idea. And as a result this internal output impedance would behave like the ”series” resistor or that’s incorrect?

It made my thoughts clearer now. Tony EE rocketscientist 62k 2 21
