PGA didn't work well
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?
