I am generating a sinewave and outputting it directly to an MX7224, an 8 bit DAC. From there, I want to amplify it and send it to an 8 ohm speaker. I have an LM386, but it distorts the signal by adding higher frequency components and making it more square than sinusoidal. The entire circuit runs on 5V. I'd like to have it be audible throughout a quiet room.
Could someone point me towards a suitable LM386 set up for this situation, because the ones I have used before (the applications on the datasheet) haven't sounded too great. Thanks!
