    Vssa reference

    user_94391782

      Hi,

         

      need to kno what is the actual minimum value of voltage Vssa in CY3866AXI-040. the datasheet specifies it as gnd +/- 0.5V but in the attached project of PGA the swing am seeing in the output is much below gnd at high gain value.Kindly see the attached file.

         

      I've also seen the swing with a naked opamp in the same project, amplification is seen peak to peak an dnot above gnd.
