NOTES:

* Specification same as preceding model.

(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.

(4) Input offset term included in output offset specification.

(5) V

is the nominal input voltage that results in a 0V output.
