VREF- as shown in Figure 12. For any input range
other than the 2.5 V range, the modulator gain error
can not be completely calibrated out. This is due to
the lack of an accurate full scale voltage internal to
the chips. The 2.5 V range is an exception because
the external reference voltage is 2.5 V nominal and
is used as the full scale voltage. In addition, when
self-calibration of gain is performed in the 25 mV,
55 mV, and 100 mV input ranges, the instrumenta-
tion amplifier’s gain is not calibrated. These two
factors can leave the converters with a gain error of
up to ±20% after self-calibration of gain. There-
fore, a system gain is required to get better accura-
cy, except for the 2.5 V range.
System Calibration
For the system calibration functions, the user must
supply the converters calibration signals which rep-
resent ground and full scale. When a system offset
calibration is performed, a ground reference signal
must be applied to the converter. See Figures 13
and 14. As shown in Figures 15 and 16, the user
must input a signal representing the positive full
scale point to perform a system gain calibration. In
either case, the calibration signals must be within
the specified calibration limits for each specific
calibration step (refer to the System Calibration
Specifications).
