Notes: 7. All outputs unloaded. All inputs CMOS levels.
8. T=VREF/(Gx25), where T is the full scale span, where VREF is the differential voltage across
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.
9. When calibrated.
10. Voffset is the offset corrected by the offset calibration routine. Voffset may be as large as 2T.
