NOTES

1Adjustable to zero. See Figures 5 and 6.

2% FSR = percent of full-scale range.

3Includes internal voltage reference error.

4Includes internal voltage reference drift.

5Excludes internal voltage reference drift.

6With maximum external load applied.

Specifications shown in boldface are tested on all devices at final electrical test with worst case supply voltages at TMIN, 25°C and TMAX. Results from those tests are used to

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.
