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) Input offset term included in output offset specification.
