[quote user="Bob Benjamin"]5.5V is the maximum voltage that can be applied to the device before damage will occur. This is a process limitation. The ESD cells are slightly different between the analog and digital input pins. You will note that the analog input pins has the VDD+0.3V maximum requirement. Also note that this does not mean that you can apply up to 5.8V if the VDD supply is 5.5V. Any input beyond 5.5V will damage the device.[/quote]
Well is there any functional difference between ESD diodes & clamping didoes? Because if I assume both same then common mode Vin(Max) of 10V with series resistor of 1Kohm limiting continuous current of 10mA is supposed to work.
In case I need additional protection for thermocouple measurement with ADS1118 what will be your suggestion ?
How ADS1120 is different for this protection?
