†
All characteristics are measured under open-loop conditions with zero common-mode input voltage unless otherwise specified. Unless otherwise
noted, an output load resistor is connected from the output to ground and has the following values: for low bias, R
L
= 1 MΩ, for medium bias,
R
L
= 100 kΩ, and for high bias, R
L
= 10 kΩ.

Full range is 0°C to 70°C.
