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?

BR

PSoC inputs must always stay >0 V. Please see solution in this thread
