Squeezing a higher resolution from U575 DAC

[Skfir]

Hello everyone! Sorry for a dumb question - I am a piano major. I want to squeeze extra 2-3 bits of the built in DAC and so I have heard that it was possible to increase a DAC resolution by adding jitter. Could please anyone share a link to some not-too-difficult article that explains how to do that and how it works?

Thank you!

I guess you mean "dither"? Which would be adding noise to a signal to mask quantization error at low resolution for low level signals.

Jitter is usually used to describe clock noise (time error from edge to edge).

For the basics of audio engineering: search the web...

Anyway, what you need is oversampling, and then analog filtering.

Even simpler, connect an audio DAC via SAI / I2S.

Thank you! Do you mean SPI & I2C? Or what you have mentioned are some special protocols?
