While the variation in offset with supply voltage is propor-
tional to VCC (see Figure 4), several characteristics of this
variation can be used to eliminate the effects. First, the
variation with respect to supply voltage is linear. Second,
themagnitudeoftheoffseterrordecreaseswithdecreased
supply voltage. Third, the offset error in microvolts is al-
most independent with reference and therefore the offset
in ppm is inverse proportional to reference voltage. As a
result, by tying VCC to VREF , the variation with supply can
be reduced, see Figure 6. The variation with supply is less
than 15ppm over the entire 2.7V to 5.5V supply range.
