    Implementing Differential amplifier on PSoC 1

       Hi,

         

          I am trying to implement a differential amplifier to convert an input signal range of 1-5V to 0-4 V. I tried it using 2 back to back PGAs with first stage (Gain=1,ref Vss) providing 1V ref to second stage(Gain=1) to which input signal of 1-5 volts is applied.But this did not work as expected.

         

          Has anyone implemented it before?Please help me out.
