Hello everyone,
I am confused to make Audio output amplifier for mono. I used LM386 amplifier.
The input of data comes from processor analog pin.
I show the image.
however, I do not really understand whether I need RC filter in the output amplifier.
Is there anyone have experience on this, please help me ?
How to make a correct and good audio output amplifier in detail?
Thanks for your help.
I will be really appreciate this.![AudioOpAmp.png AudioOpAmp.png](https://www.edaboard.com/data/attachments/7/7597-6b907d7e896cf1412c87800434c4a655.jpg)
