(1)

All characteristics are measured with zero common-mode input voltage, unless otherwise specified.

(2)

The voltage at either input or common-mode can not be allowed to go negative by more than 0.3V. The upper end of the common-

mode voltage range is VCC+ – 1.5V at 25°C, but either or both inputs can go to 30V without damage.
