FIGURE 3. Relationship of Offset and Gain Adjustments. GAIN AND OFFSET ADJUSTMENTS Figure 3 illustrates the relationship of offset and gain adjust- ments for a unipolar connected D/A converter. Offset should be adjusted first to avoid interaction of adjustments. See Table I for calibration values and codes. These adjustments have a minimum range of ±0.3%. FIGURE 2.
