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
