Hello,
I'm a very beginner in electronics and want to make an audio amplifier circuit. The circuit will be based in the TDA2030 IC.
I reproduced the circuit "Typical Application with Split Power Supply" as in the datasheet ( https://www.electro-tech-online.com/custompdfs/2012/04/tda2030.pdf ).
I put in the circuit a wave generator giving a sine wave of 447mV of peak, as specified in https://en.wikipedia.org/wiki/Line_level for "consumer audio".
Although, the output wave is saturating, and I think it is a problem.
I took a screenshot from the circuit being simulated in Multisim 12
**broken link removed**
I changed the 22k resistor to a potentiometer. I think the problem is in that resistor's value, but I would like your opinion. The wave is fine when I make the value of the 22k resistor lower.
Could someone help me solving this issue? (is that really an issue?)
Thank you all
