PSoC 4 MCU

Anonymous
Not applicable

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 http://www.cypress.com/forum/psoc-3-device-programming/floating-psoc#comment-352571
