Electrical characteristics
Absolute maximum ratings
This product contains devices to protect the inputs against damage due to high static
voltages; however it is advisable to take normal precaution to avoid application of any
voltage higher than the specified maximum rated voltages.

And, solving first equations:
K = P
K is a constant for the particular, which can be determined through last equation by
measuring P
Using this value of K, the value of P
