LTC2497 - Protection and Low Voltage Conversion Divider Logic for Differential Input & ADC Conversion Logic

Hi ADI Team,
We are using LT2497 in a SCADA Application to read the Analog Voltage from Different Field. Please Guide us on

How to Protect the Analog Signal from Field ?
How to Low Convert the Higher Voltage Differential Analog Input Range(0-20V) to 0-5V using Resistor Divider (Regarding Reference) ?
How will be the ADC Conversion will work?

Looking Forward for Your Support.



Updated the Voltage range
