    PSOC4: ADC Diff Mode





      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?
