Specifications shown in boldface are tested on all devices at final electrical test with worst case supply voltages at T
calculate outgoing quality levels. All min and max specifications are guaranteed, although only those shown in boldface are tested.
Specifications subject to change without notice.
Adjustable to zero. See Figures 5 and 6.
Includes internal voltage reference error.
Includes internal voltage reference drift.
Excludes internal voltage reference drift.
With maximum external load applied.
