The datasheet of AD7606 says that input voltage can be clamped at 16.5V. My question is if applying a 18V DC voltage at input terminal of AD7606, what will happen? and how about the condition when 20V DC applied, can the chip be damaged? And what's the max input current limited if the external voltage input exceed +/-16.5V.
It will be great if you can provide some guideline on how to calculate it.
