NOTES
1
Least Significant Bit.
2
Adjustable to zero with external trim potentiometer.
3
FSR means “Full Scale Range” and is 20 V for the ±10 V range and 10 V for the ± 5 V range.
4
Gain and offset errors adjusted to zero at 25°C.
5

F
= 0, see Figure 3a.
6
Maximum with no degradation of specification, must be a constant load.
7
A 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.
