NOTES
1Nonlinearity is defined as deviation from a straight line from zero to full scale, expressed as a fraction of full scale.
2Full-scale calibration error adjustable to zero.
3Measured at full-scale output frequency of 100 kHz.
4Refer to F/V conversion section of the text.
5Referred to digital ground.
Specifications subject to change without notice.
Specifications shown in boldface are tested on all production units at final electrical test. Results from those test 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.
