PCM5102 pcm2707 board
Well I picked up a pair of M-Audio BX5A Deluxe on black Friday and wanted to get a dac made for them.
This is an alpha version of what I have planned. Eventually it will have power control for the speakers, multisource (src4392) inputs, balanced outputs (pcm1792), and a linear psu.
This board includes the following:
USB B Jack
Dual 1/4" phono jacks (mono unbalanced)
reg102 to regulate down to 5v
dual TPS79133 to regulate down to 3.3v (one per IC)
PCM5102 with FILT control
Let me know what you think. I am going to be going over everything one more time then will be having some boards made.
I think your board works well, since I made some board similar to your schematic.
I constructed my board in as below.
Input: mini-USB B (bus powered)
I/F : PCM2707 (USB to I2S)
Isolator : ISO7240M / ISO7640FM
DAC : PCM5102 (each 3.3V supplies(DVDD, AVDD, CPVDD) are generated by TPS79133+DCR010505 )
Buffer : BUF634 (+/-9V supply generated by TPS7A4901/3001+DCP020515)
This board currently works very well.
Hi, I'm new here.
My group doing USB Audio Box. Can I know is it possible if we change the USB to the connection like the one use in iphone?
Ivatha, can you post the schematic of your USB DAC?
I think to make something familiar with dc/dc switching regulators followed by low noise linear regulators.
