    PSOC4: ADC Diff Mode

    murat.temiz@ebv.com

      Hi,

         

       

         

      I would like to use the PSoC 4100S-Family. But I have some requirements acc. the ADC Module

         

      - sample and conversion time: min. 7µs

         

      - external reference voltage input for ADC

         

                               switches between 1.3V and 2.5V
                               no internal connection to VDDA

         

        -  differential ADC measuring

         

                              1 channel
                              programmable gain amplifier (gain: 4)
                             down to -0.7V input voltage at one input pins

         

      My question is, how can I measured down to the - 0,7 V on the ADC input? Is it possible?
