System Calibration Specifications
Positive Full Scale Calibration Range
Maximum Ratiometric Offset Calibration Range
Differential Input Voltage Range
10. V offset is the offset corrected by the offset calibration routine. V offset may be as large as 2T.
8. T=VREF/(Gx25), where T is the full scale span, where VREF is the differential voltage across
9. When calibrated.
VREF+ and VREF- in volts, and G is the gain setting of the second gain block. G can be set
to 1, 2, 4, 8. This sets the overall gain to 25, 50, 100, 200. The gain can then be fine tuned by
using the calibration of the full scale point.
