As certain people are aware, I've been working on a DAC for some time. I've come to a crossroads, as I've found a way to (somewhat) reasonably have some boards manufactured. To do this economically, I'd have to modularize the design a bit. The question is, is it worth it? Would anyone be interested in the boards?
Some details:
192kHz upsampling via AD1896
192kHz DAC, AD1853
TI DIR1703 FIFO reciever IC
AD8561 or LT1016 input comparator
Analog attenuation via relays and fixed resistors (optional)
Regulators onboard for each IC
Very generous allowances for bypassing
No routing through groundplane
This board is very SMT-intensive; it had to be for best quality. The boards would be professionally manufactured 2-layer throughhole plated with SMOBC soldermask.
I will be publishing I/V outlines, but not having boards manufactured.
I'm thinking $30 for the boards, less if I end up with some definites by the time I place an order. Anyone interested?
