* Full range (Min. to Max.) is -40 C to +125 C, All characteristics are measured with zero common-mode input
voltage unless otherwise specified.
** The voltage at either input or common-mode should not be allowed to go negative by more than 0.3V. The upper
end of the common-mode voltage range is VCC-1.5V, but either or both inputs can go to 30V without damage.
