Transient Response Time
Transient response is defined as the time it takes for the ADC
to reacquire the analog input after a transient from 10% above
negative full scale to 10% below positive full scale.

Out-of-Range Recovery Time
Out-of-range recovery time is the time it takes for the ADC to
reacquire the analog input after a transient from 10% above
positive full scale to 10% above negative full scale, or from 10%
below negative full scale to 10% below positive full scale.
