ELECTRICAL CHARACTERISTICS
Boldface limits apply over the specified temperature range: T
At T
(1) RTI means Referred-to-Input.
(2) Initial resistor variation is 30% with an additional –2200ppm/ C temperature coefficient.
(3) For output behavior when V
(4) Total output error includes effects of gain error and V
(5) See typical characteristic curve Output Swing vs Output Current and Application Information section
(6) Ensured by design; not production tested.
