24-03-2010 PCB layout review held
A very useful review (Review24032010) has been held that introduced several improvements. Overall the layout was already fine and would have given a working board. Certain of the suggested changes will make the layout better, likely improving SNR and EMC features. Other changes will improve the production process or are just cosmetical.

2-03-2010 Schematics review held
The schematics review (Review02032010) revealed some serious problems and signalled other issues that will make the design more robust. Other comments will make that the documentation will be improved. The changes will be implemented before finalising the PCB layout.

2-12-2009 Project on hold
SNR level too high with PGA. User need is to have programmable offset instead of programmable gain (S. Deghaye).
