Figure 4. Offset vs VCC
Figure 5. Offset vs Temperature
Figure 6. Offset vs VCC (VREF = VCC)
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,
the magnitude of the offset error decreases with de-
creased supply voltage. Third, the offset error in micro-
volts is almost 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.
