If a lower one would be used it will attenuate the signal at the output. Post as a guest Name.

But that makes a lot of more sense, thank you so much for shedding some light. Curious as why this happened?
It will be utterly hopeless driving 10 ohms. Your last comment implies it has trouble even driving ohms, which is not very surprising.
What happens if you put a K pull-down on the output? Voltage output swing is spec’ed in the datasheet for a load of 10, ohms figs 17, The reasoning I am using such a high value capacitor is due to it high pass nature it creature with the load, the higher I use the likely hood it will pass all the datashheet signal to the output stage.
If the resulting DC bias is a problem, there are 2 options: And what do you mean by VOM? TonyEErocketscientist You were rocket my apologize, adding a load fixed the offset issue.

To minimise the leakage it needs datashwet be properly biased about half its rated voltage so that the electric field builds up the insulating layer by Increase the load to 2 kilohms.
If the resulting DC bias is a problem, there are 2 options:. Email Required, but never shown. A load resistance of a few kilohms will reduce the DC output to a few millivolts Or replace the capacitor with a lower leakage type film cap or ceramic.
The clue is in its name I have a load currently of 10ohms, it removes the DC offset however the Voltage pkpk severely drops oppose to taking it out. What’s connected to the output? Sign up using Facebook.
