This issue is for tracking found mistakes/issues in DiPho_AFE.PrjPcb

    • [x] Wrong resistor values in feedback divider of MCP1726 LDO (DS21936C page 14) - change to 11k5 and 120k respectively

    • [x] Change multiplexer IC to something with better leakage current characteristic, ex. Vishay DG4052E (50nA max) or Maxim MAX4052 (1nA - 50nA max, depending on version)
    • [x] Seperate the LOG amp and TIA version to two different PCBs.
    • [x] Fix the wrong connections of offset voltage in TIA circuit.
