Audio Analogue to Digital Converter AD2496

Posted on Feb 4, 2014

The latest circuit diagram of the AD2496 is shown here. All modifacations I intended and described in the article about the prototype have been implemented. Additionally I introduced two current compensated chokes for higher EMV immunity. Not that I experienced them to be necessary, but I know about the extreme requirements of the relevant regulat

ions. And this design is meant to be professional. from May `06: I also found out that the TOTX141 has to be replaced by a TOTX179P because the TOTX141 is a 3. 3 V type (which does actually not prevent it from working in all my units). Except its operating voltage of 5 V the TOTX179P is fully compatible. Also, the discontinued CS8405A is replaced by the fully compatible CS8406. I rearranged the DIP-switches so that the 4 relevant ones are on the leftmost side. The others are for experimental use and not meant to be populated in an actual device. For my units I used an SG206 case from the (German) company Fischer Elektronik. Front panel, case and board are directly fixed to each other using the element 5. 60. 422 from the (German) company Ettinger, available at BG rklin. You need not necessarily use the case I used. The board can easily be built into other cases. For this case I provided a detailed dimensional drawing, either as a GIF file or as a PDF file. You will see there how the board is fixed within the SG206 and how it can alternatively be fixed directly to other front panels. Of course you may also use four stand-offs, pillars or distance tubes to fix the board on the bottom of your case. The drilling positions can be found in the dimensional drawing, too. The front panel is manufactured by Schaeffer AG (in Europe) and is available in the US from Front Panel Express, LLC, too. You need the design file for the front...
