I am going to build a small headphone amplifier based on TDA2822 that runs on 3V. It is going to amplify an electric guitar into the headphones for night-time practicing. Guitar has volume pot so I am thinking that the amplifier does not really need one. Unfortunately, I am noob when it comes to design, schematics, etc so I do not really know what would be the best approach (having the potentiometer in the amp or not). Looking for your input.
Thanks.
Thanks.
Thanks for reply. That amp would be strictly for the guitar. The only other source that I could use it for is the iPod which also can control volume. I was thinking that having just one potentiometer would be better. Well, there is already spot on the PCB for the pot so that part is easy.
