NOTES:

(1) Output Range and Supply Current specifications are based on minimum output load resistance.

Minimum output load resistance is calculated by V

OUT

, where P

is the Output Effective Available

Power that guarantees output range, accuracy, and linearity specifications.

(2) Accuracy includes the effects of repeatability, hysteresis, and linearity.

(3) Nonlinearity is calculated using the best-fit straight line method.
