Yes, somethink like this. As you see, it's not a reasonable filter for a general audio amplifier. But where did you get the filter circuit? Why don't you simply refer to a LM386 datasheet example circuit?based on my software simulation, the cut off frequency is only about 1.5kHz
Doesn't sound like a specification.How to make a correct and good audio output amplifier in detail?
Don't start new threads with the same content, it is not allowed.
I have updated the title of this thread and your posts are merged. [alexan_e]
It's O.K. to drive it through a low pass.LM386 is a linear audio amplifier.....not like a class-d type audio amplifier which can be driven by a pwm.....you cant reproduce the exact audio with this......
Do you have an example of the circuit ?Alternatively, you can feed the pwm signal to a push-pull switch and place a LC filter bef"ore the speaker to suppress the 44 kHz (class-D operation)."
