Hw implemtation of preamlifier from vwcdpic projet originaly designed for boosting audio signal. This is only my HW implementation, as this is my hobby: doing it as small as it can be, and still be able to make it at home. Used compenents are: 0805 SMD resistors, so8 opamp (tl072, nee5532 compatible, also lot of others, can be swaped), ele. caps as input/outpu, tamtalum caps on power line, plus inductor for noise suppresion
originaly, I designated vwcdpic boards with this amp, but ground loops always catch you... so I split board and do more optimalization, to make it as small as posible.
I personaly use this in my car,
as always, I do not made this for profit, simly, I ordered something for me, and dirtyPCB leave me 10boards as spare :) so, I populated it, and here you can buy it
for more info(assamble, BOM) look at documentation link
any question are welcome
