(1)
All limits are specified by testing or statistical analysis.
(2)
Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary
over time and will also depend on the application and configuration. The typical values are not tested and are not specified on shipped
production material.
(3)
The input common-mode voltage of either input should not be permitted to go below the negative rail by more than 0.3V. The upper end
of the common-mode voltage range is VS - 1.5V at 25°C.
