Hi Sir,

How about BB DIR1703 + AD1895 + AD1853 circuit connection.

The DIR1703 is too difficult to make all kind of sampling frequency.

If I only need 44.1/ 16 bit --> (up convert by 1895) to 192/24

How to connect.

Many Thanks.

nFORCE

thanks very much , Peter Daniel and jwb, you are helpful!

i fact i want to design a DAC which can let the user choose re-clock or not, but i still reasching some information

from the data sheet, i think CS43122 have a higher preformance and simpler circuit, right?

so i want to do the design of cs43122
but it use balance output. i am thinking how to convert the balance out to RCA out.
i have find a circuit from AD, but i dont know is it good or not.
because it base on the AD- OP-amp to design, but i want to use TI 's op-amp. since TI's OP-amp can be gotten more easy!

Default If you only want one sampling frequency.....

Then perhaps you want the DIR1701.

What Jocko said is right: you don't want the CS8420 just to do one frequency. It requires too many external components and generally a lot of bother.

Also I've built a DAC with 4x1704 and I've built another on with CS43122. The 1704 DAC sounds better.
