The digital circuit power supply uses LT1963EQ to supply power. Lt1963 has the advantage of low ripple of 1mv and a current of 1.5a.
The digital receiving circuit AK4118eq, well-known in the industry, will not say much.
The analog amplifier circuit is directly transplanted to the mature circuit of our PCM1792 DSDMINI DAC. If you want to know how to evaluate it, you can take a look at it. I won't say much here.
