I just do a design of lm386-based audio amplifier circuit

[erinxie]

Hi everyone, I just did a design of lm386 audio amplifier circuit and get a problem, 

Design steps:

• First, think about the chip based on its function, thus designing the circuit
  
• Second, to understand the nature of the chip, characteristics.
  
• Third, use DXP software to draw the circuit schematic.
  

I could not use DXP software, how to fix?

You need to supply a link/url to the DXP software you are using. There are numerous software packages called DXP.

I think it's not possible to give a good answer without knowing which specific DXP softaware you're using and what error you're facing.

I used Lm386 as an audio amplifier, 9V , and when I check the output waveform it amplifies but it was clipped. I just copied the circuit diagram on its datasheet. How to fix this? Any advice there in making an audio amplifier with good sound quality ?

You can add a decoupling capacitor. Sometimes, the output waveform can be clipped due to noise in the power supply. Adding a decoupling capacitor between the power supply and the ground can help reduce the noise and improve the output waveform.

Thanks! I have fixed this problem
