    PGA didn't work well

    romil.argi

      hi,

         

      i configure PGA with this configuration :  PGA_1_Start(); PGA_1_SetGain(PGA_1_GAIN_04);

         

      And the schematic is attach. 

         

      I put in P60 a sinwave with 0.5 volt peak to peak(vpp) and the P62 i only have approximately 1.2 vpp.

         

      If i set Gain=08 i get on P62  approximately 2.1 vpp,

         

      is it normal?
