*% FSR = percent of full-scale range.
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.
