NOTES:
4. The R1/R2 divider may be across either VO or V(ref). If the divider is across V(ref), use figure numbers without parentheses. If the
divider is across VO, use the figure numbers in parentheses.
6. For Figures 3, 8, and 10, the device requires a minimum of 9 V between VCC+ and VCC– when VO is equal to or more positive than
–9 V.
