    as per above attached circuit can any one explain what does than means to is it a filter or what?

    this is a current sense of h-bridge sensed back to micro controller ADC.

    R9 is a load on the sensor output.
    R8/C16 are a low pass filter to reduce fast variation in the measured voltage (= average it over a period) so it gives a more constant reading.
    The pin on the IC will be an analog input to read the voltage.
