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
2 /P
E
, where P
E
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) V
Z
is the nominal input voltage that results in a 0V output.
