NOTES
1Least Significant Bit.
2Adjustable to zero with external trim potentiometer.
3FSR means “Full Scale Range” and is 20 V for the 10 V range and 10 V for the 5 V range.
4Gain and offset errors adjusted to zero at 25°C.
5CF = 0, see Figure 3a.
6Maximum with no degradation of specification, must be a constant load.
7A minimum of 12.3 V is required for a 10 V full scale output and 11.4 V is required for all other voltage ranges.
Specifications shown in boldface are tested on all production units at final electrical test. 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 on all production units.
Specifications subject to change without notice.
