@OP, you still haven't told us what you really want to do
Thank you for all the information. Sorry for cross Posting. Moreover, I wanted to create/manipulate a timer function that can allow better sound quality, because Ive seen individuals creating really good quality sound with a R2R resister ladder.
Sorry again for the many question, however reading more forums i found that you can "If you need 16 bits, you can use 2 R2R ladders and tie the output of the low byte R2R to the input of the high byte R2R and get a clean 16 bit analog output". Do y'all think it would increase the audio signal, because currently I'm using a 1 R2R resistor ladder? But the built in ADC is 8 bit, so will that aswell cause problems?
Thank you
