(1) See the VVIN_UVLOP_RISING and VVIN_ UVLOP_FALLING electrical characteristics for the miminum operational VVIN. Becasue VVIN_ UVLOP_FALLING < 8V, VVIN can operate at 8V as long as VVIN > VVIN_UVLOP_RISING during start up.
(2) See the (VDD-VEE) and (COM-VEE) Load Recommended Operating Area section for maximum rated values across temperature and VVIN conditions for different (VDD-VEE) and (COM-VEE) output voltage settings.
