Here I have the image of a signal in the datssheet of U2, and the output is shown in green in the graph sorry for the poor quality. It made my thoughts clearer now.

I would design for 10 mA maximum. 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.

However, this is a “small signal” graph. The output impedance assessment in your question I think is based on this: The low output impedance you quoted is conditional on the output stage not being overloaded. I’ve also checked the TL output resistance and it’s about 0. I guess I’ve gotten the idea. Iron Maiden 7. The absolute continuous ratings for the TL state that the output short-circuit duration is ‘continuous’.

It has been clearer since the first comment up to now. 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: Email Required, but never shown.

Andy aka k 10 Post as a guest Name. Now I have the same circuit but with that 1N zener connected across and the output signal behaves like below: Looking at Figure 7 the positive current limit applicable to your design is 20 mA but datsaheet dependent.

Not sure if this answers your comment? Home Questions Tags Users Unanswered. So, what exactly is going on in this circuit? What exactly would be the loading in this case? By using our site, you datasheet that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Could I think of the situation as a dynamic output impedance being changed when the current begins to be limited by the opamp? It’s a calculated graph based on the open-loop gain graph and the amount of gain a particular op-amp may 1n728 configured for. Sign up using Facebook. Thank you for any help.

The small signal output impedance is due to the op-amp open-loop gain not being infinite. I tried that on real circuits with TL OpAmp and the same happened. And as a result this internal output impedance would behave like the ”series” resistor or that’s incorrect?

Ratasheet means that there is current limiting built in. In my understanding the zener should face the whole sinusoidal wave since there’s no resistor in series to share the remaining voltage datashest. If you have a simulator handy it’s easy to simulate. Shouldn’t a zener have a series resistor in order to clamp correctly? 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.

Tony EE rocketscientist 62k 2 21 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. 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 1n47228 to become clamped at around the zener point.
