    Interffacing PSoC 5 kit with high impedance sensors

    ruben.didane

       Hi I'm having problems reading a DC high Z signal at the analog opamp ports on the kit while acquiring it for Delsig ADC, I buffered the analog signal in a follower opamp / buffer PGA with no luck so far, what would be the best solution to deal with the high impedance? Will resistors (10M or higher) be enough or I still need an external fA opamp. I'm so far stuck and still unconvinced with the analog specs of PSoC. I'd appreciate your help. Thanks
