(1)

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

(2)

The voltage at either input or common-mode must 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.

(3)

Full range TA is –40°C to +85°C for I-suffix devices and –40°C to +105°C for K-suffix devices.
