* All characteristics are measured under open loop conditions with zero common - mode input voltage unless otherwise

specified. Full range is 0°C to 70°C.

** 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 V

- 1.5V, but either or both inputs can go to 30V without damage.
