    Hello Every One,

    I want to interface below signal to ADC of STM32F205.
    So how to interface this signal to MCU ADC pin.
    How to calculate the source impedance and what should be minimum impedance to be connected at ADC pin.
    pl find below interface circuit. My intention is to understand the interface.
