(1)

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

(2)

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

common-mode voltage range is VCC+ – 1.5 V, but either or both inputs can go to 30 V without damage.
