Do I need the isolation in my application?

Hi all

 

Sorry for asking this basic question. I am not quite familiar of the application of the isolator after reading several papers.

 

I am trying to read DC value with an ADC, which is a 16-18 bit precision one.

The ADC will communicate with a microcontroller at 160kbps.

 

The whole controller is not working under high voltage condition.

 

Do I need the isolator between the adc and the mircocontroller?

 

 

Thank you very much.

 

Best regards

Richie CHEN
