Meet this DAC's audition
My girl friend is said . Like having exchanged the small plate . Sound ( my girl friend does not understand sound ) that it is very beautiful |

| When are you going to market your product? In complete kit form? Furnished PCB? |

Hi,
Looking at the schematic, the 74HC02 is sending inverse signals of Sdata and Fsync to the right channel of AD1865 and normal ones to the left. I've seen it done in a double DAC setup with balanced output. But I don't quit understand what the data structure is in an un-balanced setup such as this one. Explanation in simple English is much appreciated.
Cheers,

No, No...
The same data on left and right. Only fsync is inverted between left and right.
This is the classical Audionote schematic.
We spoke here about this, and the nor gates could be replaced by simple inverters without major change in the final result.
Nothing very original here : I/U by a resistor, gain with a common cathode and cathode follower for the output impedance...
ECC88 I think, if we consider the psu caps : 50V + 50V, then B+<100V.
