    Hi to everybody!
    I have a problem. <_<
    I use an analog to digital converter for convert a signal from a sensor.
    This sensor is far from the ADC and I must use 4 long wire inside a metallic shield for the connection.
    Sometime an electronic discharge "hit" this metallic shield and my circuit go down.
    I must isolate my circuit from the sensor wire.

    How I can do ?

    I need also to feed the sensor.

    In total I have 4 wire:
    2 wire sensor's signal
    1 wire for +5V
    1 wire for GND

    :blink:
